Windows 10

2 Comments

The launch of Windows 10 today is a key moment for Microsoft and users of its platform. A few observations.

I like new Windows more than I had expected. I get on fine with Windows 8, though mostly on the desktop since that is where the applications are. Being able to run Store apps in a window makes a big difference though, and there is a real chance that this will kick-start Microsoft’s app platform at last. See my overview on The Register here.

Is Windows 10 ready, or rushed out too soon? The latter I fear. The desktop side is solid as far as I can tell, with the exception of the new Start menu – actually a Universal Windows Platform (UWP) app – which is a bit broken. Since this is how users launch applications that is a serious problem. Still, it might work OK for you if you have fewer than 512 application shortcuts. I have also seen issues with search within the Start menu, either not finding apps, or in one case just hanging (reboot sorted it).

It really should not be difficult to have reliable search across a tiny database.

The Windows Store is another source of problems. I tried to install the latest Twitter app, and ended up with a “Restoring user data” message that would not go away. It is frustrating because you cannot simply cancel the process and try again. At this time my event viewer filled with DCOM activation errors, which may or may not be related, but did remind me how much intricate and ancient technology remains in Windows.

Microsoft also has this mad idea that all eligible users should be upgraded automatically using a Get Windows 10 (GWX) application installed via Windows Update. From what I have heard so far, failures are common. Users who suffer a long update process that ends with an error message and return to the previous version of Windows may never try again, or next time buy a Mac.

This is exactly what you would expect from an in-place upgrade. There are simply too many variations of hardware and software, too many things to go wrong, for this to work reliably across millions of users.

These things will distract attention from what matters more, which is Microsoft steering Windows towards becoming a modern, mobile-friendly operating system. There is also a lot of good work on the business side, in security and manageability. In six months time Windows 10 will be a delight.

The coverage of Windows 10 in the general media also interests me. Never mind Microsoft’s generally strong financials, the common view is that the company is failing because of its lack of success in mobile. That may prove true, but it is not true yet.

In this light, I am still puzzled by CEO Satya Nadella’s decision to dismantle the Nokia acquisition, at huge cost. At the Build conference in April, Microsoft seemed determined to make Windows Phone work, with the universal app platform, Android runtime layer, and Objective C compiler support. The Nokia team had the skills to design and build phones. Disposing of it seems short-sighted.

If the app platform in Windows 10 does succeed, users will want to run those apps on their smartphones too.

Microsoft financials April-June 2015: loss from Nokia write-down, comments on future direction

Microsoft has reported its financials for its fourth quarter. The company made a loss of over three billion dollars ($bn 3.195) but this was because of an eight billion dollar write-down mostly on the phone business – in effect, writing off the value of its Nokia acquisition. It still has plenty of cash in the bank – over $96 bn according to its balance sheet. Perhaps it is too easy for companies of this size to make bad business decisions (I leave open whether it was the acquisition or the way it was handled that was the bad decision, but one of them was).

Here are the latest figures:

Quarter ending  June 30th 2015 vs quarter ending June 30th 2014, $millions

Segment Revenue Change Gross margin Change
Devices and Consumer Licensing 3233 -1670 2966 -1555
Computing and Gaming Hardware 1933 +591 435 +417
Phone Hardware 1234 -748 -104 -158
Devices and Consumer Other 2300 +538 594 +303
Commercial Licensing 10451 -782 9529 -769
Commercial Other 3076 +814 1350 +659

A few points to note. The confusing segment names are summarised at the end of this post. Revenue was slightly down quarter on quarter, from $bn 23.4 to 22.2, largely because of a decline in consumer Windows (weak PC sales). Commercial licensing was also down, which Microsoft attributes to the end of the XP migration boom.

Phone aside, Microsoft’s hardware is performing well, thanks to Surface Pro 3 and Xbox One. Although Xbox One has been outsold by Sony’s PlayStation 4, it is holding its own and Microsoft says that Xbox Live usage has grown by over 30% over the year. The company says this is “deeper user engagement”; another way of looking at this is that playing games without an Xbox Live subscription is often disappointing.

Microsoft’s cloud and server projects are both growing. Business cloud revenue (Office 365, Azure and Dynamics CRM) is up 106% over the year and server products up 12%.

A bright spot is that search advertising revenue grew by 21% and Bing is expected to be profitable in the next financial year. The search wars are last year’s thing but Microsoft’s determination has won it a small but viable slice of the market. It is important because the data from search is essential for high quality predictive analysis and personalisation services, which is still a coming thing (Cortana, Siri, Google Now).

In the earnings call, CEO Satya Nadella revealed some data:

  • 15 million consumer Office 365 subscribers growing by 1 million per month
  • 50,000 new SMB customers for Office 365 per month
  • Paid seats for Dynamics CRM up 140% year on year
  • 17,000 customers for Enterprise Mobility Services (Mobile Device Management)
  • Over 100% growth in Azure both in revenue and compute usage

Of Windows 10, Nadella says:

While the PC ecosystem has been under pressure recently, I do believe that Windows 10 will broaden our economic opportunity and return Windows to growth.

A short-term boost from Windows 10 would not be surprising, but does he think that Microsoft can reverse the trend from PC to mobile, or that Windows can be successful enough in the mobile category (tablets and phones) to benefit from that trend? If the latter, perhaps destroying the Nokia acquisition was not the best move (but I must not harp on about this).

On Windows 10, Nadella described three phases:

Upgrade phase: From July 29th when free Windows 10 upgrades begin.

OEM device phase: From “the fall” when Windows 10 PCs and devices go on sale.

Enterprise upgrade phase: Piloting and deployments from January 2016

Note from the last that Windows 10 is not fully business-ready yet. Enterprise Store, OneDrive for Business client, “Project Centennial” which lets you wrap Win32 apps for Store deployment, none of these are done.

How is Microsoft hoping to grow its business? CFO Amy Hood identified three areas, in response to a question on operational expenditure:

The first one is Windows 10. The second is the first party hardware where we just had such terrific performance again this Q4. And then, finally, the third bucket was about accelerating our commercial cloud leads.

Of these, the third looks a sure bet, the other two are more speculative. Microsoft will continue to be a fascinating business to watch.

Microsoft’s segments summarised

Devices and Consumer Licensing: non-volume and non-subscription licensing of Windows, Office, Windows Phone, and “ related patent licensing; and certain other patent licensing revenue” – all those Android royalties?

Computing and Gaming Hardware: the Xbox One and 360, Xbox Live subscriptions, Surface, and Microsoft PC accessories.

Devices and Consumer Other: Resale, including Windows Store, Xbox Live transactions (other than subscriptions), Windows Phone Marketplace; search advertising; display advertising; Office 365 Home Premium subscriptions; Microsoft Studios (games), retail stores.

Commercial Licensing: server products, including Windows Server, Microsoft SQL Server, Visual Studio, System Center, and Windows Embedded; volume licensing of Windows, Office, Exchange, SharePoint, and Lync; Microsoft Dynamics business solutions, excluding Dynamics CRM Online; Skype.

Commercial Other: Enterprise Services, including support and consulting; Office 365 (excluding Office 365 Home Premium), other Microsoft Office online offerings, and Dynamics CRM Online; Windows Azure.

Microsoft completes Visual Studio 2015

Microsoft has completed Visual Studio 2015, the latest version of its all-encompassing development tool. You can download it here. Today is also the release day for TypeScript 1.5 (a language which compiles to JavaScript)

image

Windows 10 is released in just 9 days, so all eyes will be on this and its new/old app platform – the Universal Windows Platform, based on the Windows Runtime, as found in Windows 8, but considerably revised so that developers can in theory write one app and run it on any Windows 10 device, from PC to tablet to phone to Xbox to HoloLens, and sell or distribute it from a unified Windows Store.

Microsoft CEO Satya Nadella recently confirmed that the Windows Store is a key part of the Windows 10 strategy:

Why then make all these changes to the Start Menu with Windows 10? It’s not because I just want to bring back the old. It’s because that’s the best way to improve the liquidity [of] our store. Windows 8 was great except that nobody discovered the store. In Windows 10, the store is right there and done in a tasteful way.

The Store is more visible in Windows 10 than in 8 because in Windows 10 there are no longer two separate environments (Metro and desktop), but only one (desktop). Windows Runtime apps run in desktop windows. This makes the experience a little worse for tablet users, but the advantage is that now desktop users are more likely to interact with the Store, and more likely to use the apps they install, since they run in a familiar environment.

Another key change is “Project Centennial”, which I wrote up for the Register here. This lets developers package desktop apps for delivery from the Store, using app virtualisation (based on an Enterprise product called App-V). If Microsoft gets this right, Project Centennial will be the preferred way to deliver most desktop apps, since it is both easier and safer for the user.

If the Store does take off (and if it does not, Windows 10 will in part have failed), then Visual Studio will be the key tool for created or repackaging apps for Windows.

Windows 10 is important, but so too is Azure, Microsoft’s cloud platform. Visual Studio has a key role here, too. Microsoft has an entire stack, including Windows as both operating system and development environment, Visual Studio for coding and testing, and Azure for hosting cloud applications. Since the early days of Azure, the development experience has improved, so that with a modest understanding of the ASP.NET MVC framework you can go from an idea to a working demo, hosted on Azure, that you can show customers, in a short space of time.

There is also a new Cloud Explorer in Visual Studio which lets you view Azure resources from the IDE.

image

Mobile is Microsoft’s weak point, but the the company has made efforts to support Android and iOS both through mobile service back-ends hosted on Azure, and by supporting various approaches to building cross-platform apps. Visual Studio 2015 includes Xamarin project types, though out of the box these just tell you to go and install Xamarin, which lets you build Android and iOS apps with C#, subject to a separate Xamarin subscription.

Another option is to use Microsoft’s new iOS tools to code in Visual Studio while targeting Apple’s mobile platform, though this does require a Mac running a remote agent.

There is also Visual Studio Tools for Apache Cordova, where you code in JavaScript and wrap the results as native apps for both Windows and mobile platforms.

Visual Studio comes with an Android emulator, based on Hyper-V, for debugging either Xamarin or Cordova apps. Xamarin also offers its own emulator and I am not sure how these compare.

In addition to the above, Visual Studio 2015 introduces C# 6.0, Visual Basic 12, the Roslyn compiler platform which enables new IDE features, and .NET Core which is an open source, cross-platform fork of the .NET Framework. Thanks to .NET Core, the latest version of ASP.NET runs on Mac and Linux as well as Windows.

Despite Microsoft’s new cross-platform focus, Visual Studio itself runs only on Windows. In a world of Mac-wielding developers that is a problem, so the company has come up with Visual Studio code, an editor with some IDE features that runs on Window, Mac and Linux. Other options for non-Windows developers are to run Windows in an emulator such as Parallels, or on a virtual machine hosted in the code (Azure has suitable pre-baked images with Visual Studio), or to use third-party tools.

Visual Studio is a critical product then, but is it really done? Although you can download the final product today, many parts are not available (Project Centennial) or still in beta (ASP.NET 5 is beta 5). This is a milestone though, and credit to the team for bringing it out in advance of Windows 10 (I recall some Windows releases where Visual Studio was still in preview on release day).

Windows Phone puzzles: strategy, what strategy?

Today Microsoft CEO Satya Nadella announced that 7,800 employees will be removed “primarily in our phone business” and that the company is taking a $7.6 billion “impairment charge … related to assets associated with the acquisition of the Nokia Devices and Services business.”

Time for a quick resume of the company’s troubled mobile efforts since the introduction of Windows Phone in October 2010:

October 2010: botched launch of Windows Phone. Despite much good work in the OS and user interface, Microsoft had lacklustre support from hardware partners, and focused on the consumer when its potential strength was in business integration with Office, Exchange etc. In addition, availability was poor; after the UK launch I went down to my local town centre and not one of the 4 or 5 mobile phone shops had it on sale.

February 2011: Nokia announces that Windows Phone will be its primary smartphone OS.

October 2011: First Nokia Windows Phones appeared. Lumia 800 was a nicely designed phone in some respects, but suffered from poor battery life and some quality issues.

Nevertheless, the Nokia Windows Phones were the first ones where the manufacturer made an effort to get the best from the OS and to tailor the hardware for it. In addition, Nokia brought excellent mapping and photography expertise, so that Windows Phones began to get some standout features.

11 July 2013: Launch of Nokia Lumia 1020 with an amazing 41MP camera.

September 2013: Microsoft announces that it will acquire Nokia.

An awkward period follows before the acquisition completes. It is meant to be business as usual at Nokia but of course it is not.

February 2014: Despite some progress, Windows Phone is not getting the market share Nokia needs, so CEO Stephen Elop announces the Nokia X range, Android smartphones with Google removed and replaced by Microsoft services. A curious announcement, since why would anyone buy Nokia X? It was not because Android works better than Windows Phone on low-end hardware; vendors have told me that the reverse is true. Nor does it make sense bearing in mind the Microsoft acquisition – though it will have been in the planning stage before that was decided.

April 2014: Microsoft’s Nokia acquisition completes. Elop joins Microsoft to head up devices. As soon as July, it is obvious that Microsoft will not be continuing with Nokia X.

September 2014: Microsoft announces Windows 10. “we are delivering one application platform for our developers … Windows 10 will deliver the right experience on the right device at the right time. It will be our most comprehensive platform ever,” says Windows VP Terry Myerson.

The new universal app platform is all very well, but it means that Windows Phone is now in stasis, waiting for Windows 10 before anything much can happen to it. There is a notable lack of new high-end phones. No phone since the Lumia 1020 has had a camera of equal resolution.

At the same time, part of the point of Windows 10 is to revive the application platform across phone and PC. If you remove the phone, the Universal Windows Platform is what, PC, Xbox (mainly a games console) and HoloLens? With a few Raspberry Pis and IoT devices thrown in?

17 June 2015: Elop leaves Microsoft following an executive re-shuffle.

8 July 2015: Suspicions that Microsoft is wavering in its commitment to Windows Phone (or Windows 10 Mobile) are confirmed by the announcement of major cuts to the phone business.

A few observations

Microsoft has given Nokia little chance of success following the acquisition. It is not quite a repeat of the Kin disaster (acquisition of Danger in February 2008, a strong company wrecked by its acquirers), but there are echoes. It is only a year and three months since the acquisition completed, and the phone range is in an uncomfortable “waiting for Windows 10” phase. What did the company expect, that a Microsoft halo effect would suddenly lift sales, even without distinctive new models?

Nokia did a much better job with Windows Phone than either Microsoft or its other hardware partners. Nokia’s retail presence, operator partnerships, and marketing, were all far superior.

The main reason for the failure of Windows Phone is the lack of apps and ecosystem, and the reason for that is that Microsoft was too late to launch; iOS and, more to the point, Android, were already well entrenched. The Windows Phone OS is pretty good, and superior to the competition in some respects; apps are easier to find, for example.

Another problem is that Windows Phone has been more successful in Europe than in the USA. This means that US-centric vendors perceive that Windows Phone has an even smaller market than in fact it has.

Bearing in mind that the app story is the biggest single problem for Windows Phone vendors, and that Windows 10 is intended to address that, it is puzzling that Microsoft is now writing off the phone division before Windows 10 has launched.

Nadella writes:

I am committed to our first-party devices including phones. However, we need to focus our phone efforts in the near term while driving reinvention. We are moving from a strategy to grow a standalone phone business to a strategy to grow and create a vibrant Windows ecosystem that includes our first-party device family.

The problem is that frail market confidence in Windows Phone will be further shaken by today’s announcement. Further, if Nadella thinks that Microsoft’s trusty hardware partners will step up their game if Lumia is given less investment, than he has forgotten their dismal performance first time around.

Does Microsoft need Windows Phone?

Microsoft has been investing in Android and iOS apps since Nadella’s appointment, and it may not have a choice about whether or not it needs a mobile OS, if it cannot find a market for it.

There some strategic issues though. Microsoft itself succeeded first with Windows on the desktop, and exploited its desktop presence to drive server products that integrated with Windows and shared its user interface and operating system.

Mobile operating systems are now ascendant, and if Microsoft has little or no presence in that market, it is vulnerable to its competitors exploiting their control of the client to drive users to their own services, rather than those run by Microsoft.

Therefore it seems to me that ceding the mobile market to Apple and Google is a strategic risk.

How to overcome “A required drive partition is missing” in Windows 8.1 reset

3 Comments

Here is the scenario: an HP all-in-one PC gets a virus and as a precaution the owner wishes to reinstall Windows.

The recovery drive on the PC is intact, but attempting to use the Windows 8.1 troubleshooting tools to “Reset your PC” (in effect reinstalling Windows) raises the error “A required drive partition is missing”.

This seems to be a common scenario in cases where the PC was supplied with Windows 8 and upgraded to Windows 8.1. The problem seems to be that Windows 8.1 makes some changes to the drive partitions that make it incompatible with the Windows 8.0 recovery partition.

Here is the workaround I used:

1. In Windows 8.1, make a recovery drive. To do this, first connect a USB drive that you are happy to have wiped. It will need a capacity of around 16GB or more. Then run Control Panel, search for “recovery”, and choose Create a recovery drive.

image

2. When creating the recovery drive, make sure the option to include the recovery partition is checked. This will copy the recovery partition from the PC to the USB drive.

3. When you are done, you will be able to boot from the USB drive. You could choose the Reset option from there, however you will still get the error. First, go to Troubleshooting and Advanced and select the command prompt. When the command prompt opens, type:

diskpart

Now type:

list disk

You will see two disks (or more) listed, one for the USB boot device, and the others the disk(s) in the PC. Select the internal boot drive. It is normally obvious from the sizes which is which. Select it by typing:

select disk n

where n is the number of the drive as shown by list disk.

WARNING: the next step will delete all data on the selected drive. If in doubt, back out and make a backup of the drive before proceeding. If something goes wrong, your PC will no longer be bootable and you will need recovery media from the manufacturer, or to buy a new copy of Windows.

Once you are happy that it is safe to delete everything from the drive, type:

clean

or

clean all

The first command does a quick removal of the partition table from the drive but does not zero the data; it will be invisible but possibly recoverable using data recovery tools. The second command zeroes all the data and takes much longer (several hours), but it is more secure, if for example you want to sell or transfer the PC.

Once this is done,reboot the PC using the USB recovery drive. Select troubleshooting, then Reset your PC. This time it will work and you will be back in Windows 8.0.

Note: This scenario is common enough that it seems to be a flaw in the Windows 8.x recovery tools. I do not understand why Microsoft has so little regard for its users attempting to recover Windows (and usually highly stressed) that it has not fixed this problem.

Note 2: What if you cannot boot into Windows 8.1 to make the recovery drive? I have not tried it, but in theory it should be possible to create a recovery drive on another PC and copy the recovery drive to it.

Installing Windows 10 on Surface 3 with Windows To Go

I am working on a review of Surface 3, Microsoft’s recently released Atom-based tablet, and wanted to try Windows 10 on the device. How to do this though without endangering the correct functioning of my loan unit?

The ideal answer seemed to be Windows To Go (WTG), which les you run Windows from a USB drive without touching what is already installed – well, apart from a setting in control panel that enables boot from Windows to Go.

image

Luckily I have an approved Windows to Go USB drive, a 32GB Kingston DataTraveler Workspace. I downloaded the Windows 10 iso (64-bit, build 10074) and used the Control Panel applet on my Windows 8 desktop (which runs the Enterprise edition) to create a WTG installation.

(There are unofficial ways to get around both the requirement for Enterprise edition, and the need for an approved USB device, but I did not have to go there).

Next, I plugged the drive into the Surface 3 and restarted. Windows 10 came up immediately. An interesting feature was that I was prompted to sign into Office 365, rather than with a Microsoft account. It all seemed to work, though Device Manager showed many missing drivers.

image

The wifi driver must have been one of them, since I had no network.

I had anticipated this problem by downloaded the surface 3 drivers from here. These were inaccessible though, since a WTG installation by default has no access to the hard drive on the host PC. I could not plug in a second USB device with the drivers on it either, since there is only one USB port on the Surface 3.

No matter, you can mount the local drives using the Windows Disk Management utility. I did that, and ran the Surface 3 Platform Installer which I had downloaded earlier. It seemed to install lots of drivers, and I was then prompted to restart.

Bad news. When trying to restart, boot failed with an “inaccessible boot device” error.

Fool that I am, I tried this operation again with a small variation. I rebuilt the WTG drive, and instead of mounting the drives on the host, I used it first on another PC, where the wifi worked straight away. I copied the Surface 3 files to the WTG drive C, then booted it on the Surface 3. Ran the Surface 3 Platform Installer, restarted, same problem “Inaccessible boot device”.

The third time, I did not run the Surface 3 Platform Installer. Instead, I installed the drivers one by one by right-clicking on the Unknown Devices in Device Manager and navigating to the Surface 3 drivers files I had downloaded using another PC. That looks better.

image

I restarted, and everything still worked. I have wifi, Bluetooth, audio, cameras and everything. So something the Platform Installer tries to do breaks WTG on my device.

The next question is whether the system will update OK when set to Fast for the Windows 10 bleeding edge. So far though, so good.

Note: there is an issue with power management. If the Surface 3 sleeps, then it seems to wake up back in Windows 8 if you leave it long enough. Not too much harm done though; restart and you are back in Windows 10.

Note 2: new builds will not install on WTG, they complain about an unsupported UEFI layout

Running ASP.NET 5.0 on Nano Server preview

2 Comments

I have been trying out Microsoft’s Nano Server Preview and wrote up initial experiences for the Register. One of the things I mentioned is that I could not get an ASP.NET app successfully deployed. After a bit more effort, and help from a member of the team, I am glad to say that I have been successful.

image

What was the problem? First, a bit of background. Nano Server does not run the .NET Framework, presumably because it has too many dependencies on pieces of Windows which Microsoft wanted to omit from this cut-down deployment. Nano Server does support .NET Core, also known as Core CLR, which is the open source fork of the .NET Framework. This enables it to run PowerShell, although with a limited range of cmdlets, and my main two ways of interacting with Nano Server are with PowerShell remoting, and Windows file sharing for copying files across.

On your development machine, you need several pieces in order to code for ASP.NET 5.0. Just installing Visual Studio 2015 RC will do, except that there is currently an incompatibility between the version of the ASP.NET 5.0 .NET Core runtime shipped with Visual Studio, and what works on Nano Server. This meant that my first effort, which was to build an empty ASP.NET 5.0 template app and publish it to the file system, failed on Nano Server with a NativeCommandError.

This meant I had to dig a bit more deeply into ASP.NET 5.0 running on .NET Core. Note that when you deploy one of these apps, you can include all the dependencies in the app directory. In other words, apps are self-hosting. The binary that enables this bit of magic is called DNX (.NET Execution Environment); it was formerly known as the K runtime.

Developers need to install the DNX SDK on their machines (Windows, Mac or Linux). There is currently a getting started guide here, though note that many of the topics in this promising documentation are as yet unwritten.

image

However, after installation you will be able to use several handy commands:

dnvm This is the .NET Version manager. You can have several versions of the DNX runtime installed and this utility lets you list them, set aliases to save typing full paths, and manage defaults.

image

dnu This is the .NET Development Utility (formerly kpm) that builds and publishes .NET Core projects. The two commands I found myself using regularly are dnu restore which downloads Nuget (.NET repository) packages and dnu publish which packages an app for deployment. Once published, you will find .cmd files in the output which you use to start the app.

dnx This is the binary which you call to run an app. On the development machine, you can use dnx . run to run the console app in the current directory and dnx . web to run the web app in the current directory.

Now, back to my deployment issues. The Visual Studio templates are all hooked to DNX beta 4, and I was informed that I needed DNX beta 5 for Nano Server. I played around with trying to get Visual Studio to target the updated DNX but ran into problems so decided to ignore Visual Studio and do everything from the command line. This should mean that it would all work on Mac and Linux as well.

I had a bit of trouble persuading DNX to update itself to the latest unstable builds; the main issue I recall is targeting the correct repository. You NuGet sources must include (currently) https://www.myget.org/F/aspnetvnext/api/v2.

Since I was not using Visual Studio, I based my samples on these, Hello World Console, MVC and Web apps that you can use for testing that everything works. My technique was to test on the development machine using dnx . web, then to use dnu publish and copy the output to Nano Server where I could run ./web.cmd in a remote PowerShell session.

Note that I found it necessary to specify the CoreClr 64-bit runtime in order to get dnu to publish the correct files. I tried to make this the default but for some reason* it reverted itself to x86:

dnu publish –runtime "c:\users\[USERNAME]\.dnx\runtime\dnx-coreclr-win-x64.1.0.0-beta5-11701"

Of course the exact runtime version to use will change soon.

If you run this command and look in the /bin/output folder you will find web.cmd, and running this should start the app. The port on which the app listens is set in project.json in the top level directory of the project source. I set this to 5001, opened that port in the Windows Firewall on the Nano Server, and got a started message on the command line. However I still could not browse to the app running on Nano Server; I got a 400 error. Even on the development machine it did not work; the browser just timed out.

It turned out that there were several issues here. On the development machine, which is running Windows 10 build 10074, I discovered to my annoyance that the web app worked fine with Internet Explorer, but not in Project Spartan, sorry Edge. I do not know why.

Support also gave me some tips to get this working on Nano Server. In order for the app to work across the network, you have to edit project.json so that localhost is replaced either with the IP number of the server, or with a *. I was also advised to add dnx.exe to the allowed apps in the firewall, but I do not think this is necessary if the port is open (it is a nuisance, since the location of dnx.exe changes for every app).

Finally I was successful.

Final observations

It seems to me that ASP.NET vNext running on .NET Core has the characteristic of many open source projects, a few dedicated people who have little time for documentation and are so close to the project that their public communications assume a fair amount of pre-knowledge. The site I referenced above does have helpful documentation though, for the few topics that are complete. Some other posts I found helpful are this series by Steve Perkins, and the troubleshooting suggestions here especially David Fowler’s post.

I like The .NET Core initiative overall since I like C# and ASP.NET MVC and now it is becoming a true cross-platform framework. That said, the code does seem to be in rapid flux and I doubt it will really be ready when Visual Studio 2015 ships. The danger I suppose is that developers will try it in the first release, find lots of problems, and never go back.

I also like the idea of running apps in Nano Server, a low-maintenance environment where you can get the isolation of a dedicated server for your app at low cost in terms of resources.

No doubt though, the lack of pieces that you expect to find on Windows Server will be an issue and I am not sure that the mainstream Microsoft developer ecosystem will take to it. Aidan Finn is not convinced, for example:

Am I really expected to deploy a headless OS onto hardware where the HCL certification has the value of a bucket with a hole in it? If I was to deploy Nano, even in cloud-scale installations, then I would need a super-HCL that stress tests all of the hardware enhancements. And I would want ALL of those hardware offloads turned OFF by default so that I can verify functionality for myself, because clearly, neither Microsoft’s HCL testers nor the OEMs are capable of even the most basic test right now.

Finn’s point is that if your headless server is having networking issues it is hard to troubleshoot, since of course remote tools will not work reliably. That said, I have personally run Hyper-V Server (which is essentially Server Core with just the Hyper-V role) with great success for several years; I started keeping notes on how to troubleshoot from the command line and found solutions to common problems. If networking fails with Nano Server then yes, you have a problem, but there is always something you can do, even if it means mounting the Nano Server VHD or VHDX on another VM. Windows Server admins have become accustomed to a local GUI though and adjusting even to Server Core has not been easy.

*the reason was that I did not use the –p argument with dnvm use which would have made it persistent

Windows 10: Moving Windows into the mobile and app era take 2, and why Windows 8 is not so bad

I attended Microsoft’s Build conference last week where there was a big focus on Windows 10. I spent some time with the latest Build 10074 which came out last week as well attending various sessions on developing for the upcoming OS. I also spoke to Corporate VP Joe Belfiore and I recommend this interview on the Reg which says a lot about Microsoft’s approach. Note that the company is determined to appeal to Windows 7 users who largely rejected Windows 8; Windows 10 is meant to feel more familiar to them.

That said, Microsoft is not backtracking on the core new feature in Windows 8, which is its new app platform, called the Windows Runtime (WinRT). In fact, in its latest guise as the Universal App Platform (UAP) it is more than ever at the forefront of Microsoft’s marketing effort.

Why is this? In essence, Microsoft needs a strong app ecosystem for Windows if it is to escape legacy status. That means apps which are store-delivered, run in a secure sandbox, install and uninstall easily, update automatically, and work on tablets as well as with keyboard and mouse. Interaction and data transfer between apps is managed through OS-controlled channels, called Contracts. Another advantage is that you do not need setup CDs or downloads when you get a new PC; your apps flow down automatically. When you think of it like this, the advantages are huge; but nevertheless the Windows 8 app platform largely failed. It is easy to enumerate some of the reasons:

  • Most users live in the Windows desktop and rarely transition to the “Metro” or “Modern” environment
  • Lack of Windows 7 compatibility makes the Windows 8 app platform unattractive to developers who want to target the majority of Windows users
  • Many users simply avoided upgrading to Windows 8, especially in business environments where they have more choice, reducing the size of the Windows 8 app market
  • Microsoft made a number of mistakes in its Windows 8 launch, including an uncompromising approach that put off new users (who felt, rightly, that “Metro” was forced upon them), lack of compelling first-party apps, and encouraging a flood of abysmal apps into the Store by prioritising quantity over quality

History will judge Windows 8 harshly, but I have some admiration for what Microsoft achieved. It is in my experience the most stable and best performing version of Windows, and despite what detractors tell you it works fine with keyboard and mouse. You have to learn a new way of doing a few things, such as finding apps in the Start screen, following which it works well.

The designers of Windows 8 took the view that the desktop and app environments should be separate. This has the advantage that apps appear in the environment they are designed for. Modern apps open up full-screen, desktop apps in a window (unless they are games that are designed to run full-screen). The disadvantage is that integration between the two environments is poor, and you lose one of the key benefits of Windows (from which it got its name), the ability to run multiple apps in resizable and overlapping windows.

Windows 10 takes the opposite approach. Modern apps run in a window just like desktop apps. The user might not realise that they are modern apps at all; they simply get the benefits of store delivery, isolation and so on, without having to think about it.

This sounds good and following the failure of the first approach, it is probably the right thing for Microsoft to do. However there are a couple of problems. One is the risk of what has been called the “uncanny valley” in an app context, where apps nearly but not quite work in the way you expect, leading to a feeling of unease or confusion. Modern apps look a little bit different from true desktop apps in Windows 10, and behave a little bit different as well. Modern apps have a different lifecycle, for example, can enter a suspended state when they do not have the focus or even be terminated by the OS if the memory is needed. A minimized desktop app keeps running, but a minimized modern app is suspended, and the developer has to take special steps if you want a task to keep running in the background.

Another issue with Windows 10 is that its attempt to recreate a Windows 8 like tablet experience is currently rather odd. Windows 10 “Tablet Mode” makes all apps run full screen, even desktop apps for which this is wholly inappropriate. Here is the Snipping Tool in Tablet Mode:

and here is the desktop Remote Desktop Connection:

Personally I find that Tablet Mode trips me up and adds little value, even when I am using a tablet without a keyboard, so I tend not to use it at all. I would prefer the Windows 8 behaviour, where Modern apps run full screen (or in a split view), but desktop apps open in a window on the desktop. Still, it illustrates the point, which is that integrating the modern and desktop environments has a downside; it is just a different set of compromises than those made for Windows 8.

Now, I do think that Microsoft is putting a more wholehearted effort into its UAP than it did for Windows 8 modern apps (even though both run on WinRT). This time around, the Store is better, the first-party apps are better (not least because we have Office), and the merging of the Windows Phone and Xbox platforms with the PC platform gives developers more incentive to come up with apps. Windows 10 is also a free upgrade for many users which must help with adoption. Even with all this, though, Microsoft has an uphill task creating a strong modern app ecosystem for Windows, and a lot of developers will take a wait and see approach.

The other huge question is how well users will take to Windows 10. Any OS upgrade has a problem to contend with, which is that users dislike change – perhaps especially what has become the Windows demographic, with business users who are by nature cautious, and many conservative consumer users. Users are contradictory of course; they dislike change, but they like things to be made better. It will take more than a Cortana demo to persuade a contented Windows 7 user that Windows 10 is something for them.

Note that I say that in full knowledge of how much potential the modern app model has to improve the Windows experience – see my third paragraph above.

Microsoft told me in San Francisco that things including Tablet Mode are still being worked on so a little time remains. It was clear at Build that there is a lot of energy and determination behind Windows 10 and the UAP so there is still room for optimism, even though it is also obvious that Windows 10 has to improve substantially on the current preview to have a chance of meeting the company’s goals.

HoloLens: a developer hands-on

1 Comment

I attended the “Holographic Academy” during Microsoft’s Build conference in San Francisco. It was aimed at developers, and we got a hands-on experience of coding a simple HoloLens app and viewing the results. We were forbidden from taking pictures so you will have to make do with my words; this also means I do not have to show myself wearing a bulky headset and staring at things you cannot see.

First, a word about HoloLens itself. The gadget is a headset that augments the real world with a 3D “projected” image. It is not really a hologram, otherwise everyone would see it, but it is a virtual hologram created by combining what you see with digital images.

The effect is uncanny, since the image you see appears to stay in one place. You can walk around it, seeing it from different angles, close up or far away, just as you could with a real image.

That said, there were a couple of issues with the experience. One is that if you went too close to a projected image, it disappeared. From memory, the minimum distance was about 18 inches. Second, the viewport where you see the augmented reality was fairly small and you could easily see around it. This is detrimental to the illusion, and sometimes made it a struggle to see as much of your hologram as you might want.

I asked about both issues and got the same response, essentially “no comment’’. This is prototype hardware, so anything could change. However, according to another journalist who attended a hands-on demo in January, the viewport has gotten smaller, suggesting that Microsoft is compromising in its effort to make the technology into a commercially viable product.

Another odd thing about the demo was that after every step, we were encouraged to whoop and cheer. There was a Microsoft “mentor” for every pair of journalists, and it seemed to me that the mentors were doing most of the whooping and cheering. It is obvious that this is a big investment for the company and I am guessing that this kind of forced enthusiasm is an effort to ensure a positive iimpression.

Lest you think I am too sceptical, let me add that the technology is genuinely amazing, with obvious potential both for gaming and business use.

The developer story

The development process involves Unity, Visual Studio, and of course the HoloLens device itself. The workflow is like this. You create an interactive 3D scene in Unity and build it, whereupon it becomes a Visual Studio project. You open the project in Visual Studio, and deploy it to HoloLens (connected over USB), just as you would to a smartphone. Once deployed, you disconnect the HoloLens and wear it in order to experience the scene you have created. Unity supports scripting in C#, running on Mono, which makes the development platform easy and familiar for Windows developers.

Our first “Holo World” project displayed a hologram at a fixed position determined by where you are when the app first runs. Next, we added the ability to move the hologram, selecting it with a wagging finger gesture, shifting our gaze to some other spot, and placing it with another wagging finger gesture. Note that for this to work, HoloLens needs to map the real world, and we tried turning on wire framing so you could see the triangles which show where HoloLens is detecting objects.

We also added a selection cursor, an image that looks like a red bagel (you can design your own cursor and import it into Unity). Other embellishments were the ability to select a sphere and make it fall to the floor and roll around, voice control to drop a sphere and then reset it back to the starting point, and then “spatial audio” that appears to emit from the hologram.

All of this was accomplished with a few lines of C# imported as scripts into Unity. The development was all guided so we did not have to think for ourselves, though I did add a custom voice command so I could say “abracadabra” instead of “reset scene”; this worked perfectly first time.

For the last experiment, we added a virtual underworld. When the sphere dropped, it exploded making a virtual pit in the floor, through which you could see a virtual world with red birds flapping around. It was also possible to enter this world, by positioning the hologram above your head and dropping a sphere from there.

HoloLens has three core inputs: gaze (where you are looking), gesture (like the finger wag) and voice. Of these, gaze and voice worked really well in our hands on, but gesture was more difficult and sometimes took several tries to get right.

At the end of the session, I had no doubt about the value of the technology. The development process looks easily accessible to developers who have the right 3D design skills, and Unity seems ideally suited for the project.

The main doubts are about how close HoloLens is to being a viable commercial product, at least in the mass market. The headset is bulky, the viewport too small, and there were some other little issues like lag between the HoloLens detection of physical objects and their actual position, if they were moving, as with a person walking around.

Watch this space though; it is going to be most interesting.

Compile Android Java, iOS Objective C apps for Windows 10 with Visual Studio: a game changer?

1 Comment

Microsoft has announced the ability to compile Windows 10 apps written in Java or C++ for Android, or in Objective C for iOS, at its Build developer conference here in San Francisco.

The Android compatibility had been widely rumoured, but the Objective C support not so much.

This is big news, but oddly the Build attendees were more excited by the HoloLens section of the keynote (3D virtual reality) than by the iOS/Android compatibility. That is partly because this is the wrong crown; these are the Windows faithful who would rather code in C#.

Another factor is that those who want Microsoft’s platform to succeed will have mixed feelings. Is the company now removing any incentive to code dedicated Windows apps that will make the most of the platform?

Details of the new capabilities are scant though we will no doubt get more details as the event progresses. A few observations though.

Microsoft is trying to fix the “app gap”, the fact that both Windows Store and Windows Phone Store (which are merging) have a poor selection of apps compared to iOS or Android. Worse, many simply ignore the platforms as too small to bother with. Lack of apps make the platforms less attractive so the situation does not improve.

The goal then is to make it easier for developers to port their code, and also perhaps to raise the quality of Windows mobile apps by enabling code sharing with the more important platforms.

There are apparently ways to add Windows-specific features if you want your ported app to work properly with the platform.

Will it work? The Amazon Fire and the Blackberry 10 precedents are not encouraging. Both platforms make it easy to port Android apps (Amazon Fire is actually a version of Android), yet the apps available in the respective app stores are still far short of what you can get for Google Android.

The reasons are various, but I would guess part of the problem is that ease of porting code does not make an unimportant platform important. Another factor is that supporting an additional platform never comes for free; there is admin and support to consider.

The strategy could help though, if Microsoft through other means makes the platform an attractive target. The primary way to do this of course is to have lots of users. VP Terry Myerson told us that Microsoft is aiming for 1 billion devices running Windows 10 within 2-3 years. If it gets there, the platform will form a strong app market and that in turn will attract developers, some of whom will be glad to be able to port their existing code.

The announcement though is not transformative on its own. Microsoft still has to drive lots of Windows 10 upgrades and sell more phones.
