Microsoft still paying the price for botched Vista with muddled development strategy

Professional Developers Conference 2003. Windows Longhorn is revealed, with three “pillars”:

  • Avalon, later named Windows Presentation Foundation (WPF)
  • Indigo, later named Windows Communication Foundation (WCF)
  • WinFS, the relational file system that was later abandoned

With the benefit of hindsight, Microsoft got many things right with the vision it set out at PDC 2003. The company saw that a revolution in user interface technology was under way, driven by the powerful graphics capabilities of modern hardware, and that the old Win32 graphics API would have to be replaced, much as Windows itself replaced DOS and the command-line. XAML and WPF was its answer, bringing together .NET, DirectX, vector graphics, XML and declarative programming to form a new, rich, presentation framework that was both designer-friendly and programmer-friendly.

Microsoft also had plans to take a cut-down version of WPF cross-platform as a browser plugin. WPF/Everywhere, which became Silverlight, was to take WPF to the Mac and to mobile devices.

I still recall the early demos of Avalon, which greatly impressed me: beautiful, rich designs which made traditional Windows applications look dated.

Unfortunately Microsoft largely failed to execute its vision. The preview of Longhorn handed out at PDC, which used Avalon for its GUI, was desperately slow.

Fast forward to April 2005, and Windows geek Paul Thurrott reports on Longhorn progress:

I’m reflecting a bit on Longhorn 5048. My thoughts are not positive, not positive at all. This is a painful build to have to deal with after a year of waiting, a step back in some ways. I hope Microsoft has surprises up their sleeves. This has the makings of a train wreck.

Thurrott was right. But why did Longhorn go backwards? Well, at some point – and I am not sure of the date, but I think sometime in 2004 – Microsoft decided that the .NET API for Longhorn was not working, performance was too bad, defects too many. The Windows build was rebased on the code for Server 2003 and most of .NET was removed, as documented by Richard Grimes.

Vista as we now know was not a success for Microsoft, though it was by no means all bad and laid the foundation for the well-received Windows 7. My point though is how this impacted Microsoft’s strategy for the client API. WPF was shipped in Longhorn, and also back-ported to Windows XP, but it was there as a runtime for custom applications, not as part of the core operating system.

One way of seeing this is that when Longhorn ran into the ground and had to be reset, the Windows team within Microsoft vowed never again to depend on .NET. While I do not know if this is correct, as a model it makes sense of what has subsequently happened with Silverlight, IE and HTML5, and Windows Phone:

  • Windows team talks up IE9 at PDC 2010 and does not mention Silverlight
  • Microsoft refuses to deliver a tablet version of Windows Phone OS with its .NET application API, favouring some future version of full Windows instead

Note that in 2008 Microsoft advertised for a job vacancy including this in the description:

We will be determining the new Windows user interface guidelines and building a platform that supports it. We’ll eliminate much of the drudgery of Win32 UI development and enable rich, graphical, animated user interface by using markup based UI and a small, high performance, native code runtime.

In other words, the Windows team has possibly been working on its own native code equivalent to XAML and WPF, or perhaps a native code runtime for XAML presentation markup. Maybe this could appear in Windows 8 and support a new touch-oriented user interface.

In the meantime though, Microsoft’s developer division has continued a strong push for .NET, Silverlight and most recently Windows Phone. Look at Visual Studio or talk to the development folk, and you still get the impression that this is the future of Windows client applications.

All this adds up to a muddled development story, which is costly when it comes to evangelising the platform.

In particular, eight years after PDC 2003 there is no clarity about Microsoft’s rich client or RIA (Rich Internet Application) designer and developer story. Is it really WPF, Silverlight and .NET, or is it some new API yet to be revealed, or will IE9 as a runtime play a key role?

There is now a little bit more evidence for this confusion and its cost; but this post is long enough and I have covered it separately.

RunRev releases LiveCode for Android preview alongside iOS, Mac, Windows, Linux

RunRev has announced a preview version of its LiveCode for Google Android, which will join existing versions for Windows, Mac, Linux, Web and iOS.

image

LiveCode is like a modern-day HyperCard, an early database and simple application builder for the Mac. It includes a graphical development environment with scripting using the LiveCode language, described by RunRev as “A very high level language”. Here is a sample:

put “The fox jumped over the lazy dog.” into theText

put “ quick brown” after word 2 of theText

The advantage is fast development, once you have become familiar with the platform.

On a quick look I noticed that LiveCode looks great for building a business-oriented client, but looks more challenging when it comes to interacting with a remote server application, though it does have support for basic http and https requests as well as socket support.

Now that Android is supported LiveCode looks interesting as a quick and easy route to cross-platform mobile apps.

Mobile app developers can register to receive the Android pre-release version today at www.runrev.com.

Viewsonic ViewPad 10 Pro does Windows and Android – but Windows first

Viewsonic has announced the ViewPad 10 Pro, a 10” tablet that runs both Microsoft Windows 7 and Google Android 2.2.

image

I saw the ViewPad 10 Pro briefly this morning here at Mobile World Congress. Specs include Intel Oak Trail chipset, 2GB RAM, 32GB storage, and front-facing camera for conferencing.

The big appeal of the ViewPad 10 Pro, successor to the ViewPad 10, is that it runs Android as well as Windows. Just tap a button, and Android appears in place of Windows.

Sounds good; but as Viewsonic explained how this works I became doubtful. Apparently Android runs in a virtual machine on top of Windows. I have nothing against virtualization; but this approach does suggest some compromises in terms of Android performance and efficiency. No matter how clever Viewsonic has been in its implementation, some resources will still be devoted to Windows during an Android session and battery life will be less good than it might be.

I can see more sense in running Android first, for the sake of its speed and efficiency on low-power hardware, and Windows in virtualization for when you need to dip into Excel or some other Windows application.

The upside of this approach is that you can switch between the two without having to to do a hard reboot.

Viewsonic says you will be able to get one of these in your hands around May 2011.

Delphi and C++ Builder XE Starter Editions announced

Embarcadero has announced Starter Editions for both Delphi XE and C++ Builder XE, rapid development environments for native Windows applications.

These are not toy versions. The main technical difference between the Starter editions and the Professional versions are the absence of UML modelling, Class Explorer and Resource Manager tools. You also miss out on code completion for HTML, Live Code Templates, Subversion support, translation manager, refactoring and unit testing.

Not a big deal: most of these lacks are either not critical or can be addressed in other ways. Most features are the same, and you can build excellent high-performance applications with these Starter Editions.

The real restriction is the licensing:

Delphi XE Starter can be used by individuals who will earn less than US $1,000 for the applications they create with Delphi, or organizations or companies with five or fewer developers and less than US$1,000 in total annual revenue. Purchase the Professional edition or higher for larger scale commercial use.

with a similar wording for C++ Builder XE Starter.

The other question: how much? At the time of writing the Starter Editions are not in the online store, but according to this article in SD Times they will be $199 each or £149 for upgrades. Ownership of a Starter Edition gives you $100 discount if you later upgrade to a higher edition.

Delphi is as good as ever, especially bearing in mind that Microsoft has no real equivalent. Visual Studio is mostly .NET-based, whereas Delphi compiles to native code; and Visual C++ is more challenging to learn and arguably less productive. It is true that developers are waiting impatiently for 64-bit Delphi and for a promised compiler for OS X (and perhaps iOS?); but in the meantime if you need to build Windows applications do not ignore it.

Update: the European price is €199 each, or upgrades for €149.

Server and Tools shine in Microsoft results – so why is Bob Muglia leaving?

Microsoft released quarterly results yesterday:

Quarter ending December 31 2010 vs quarter ending December 31 2009, $millions

Segment Revenue Change Profit Change
Client (Windows + Live) 5054 -2139 3251 -2166
Server and Tools 4390 412 1776 312
Online 691 112 -543 -80
Business (Office) 5126 612 3965 1018
Entertainment and devices 3698 1317 679 314

Microsoft highlighted strong sales for Xbox (including Kinect) as well as for Office 2010, which it said in the press release is the “fastest-selling consumer version of Office in history.”

Why is Office 2010 selling better than Office 2007? My hunch is that this is a Windows 7 side-effect. New Windows, new Office. I do think Office 2010 is a slightly better product than Office 2007, but not dramatically so. SharePoint Workspace 2010, about which I mean to post when I have a moment, is a big disappointment, with a perplexing user interface and limited functionality.

Windows 7 revenue is smaller than that of a year ago, but then again the product was released in October 2009 so this is more a reflection of its successful launch than anything else.

What impressed me most is the strong performance of Server and Tools, at a time when consolidation through virtualisation and growing interest in cloud computing might be reducing demand. Even virtual machines require an OS licence though, so maybe HP should worry more than Microsoft about that aspect.

I still think they are good figures, and make Server and Tools VP Bob Muglia’s announced departure even more puzzling. Just what was his disagreement with CEO Steve Ballmer?

Server and Tools revenue includes Windows Azure, but it sounds like Microsoft’s cloud is not generating much revenue yet. Here is what CFO Peter Klein said:

Moving on to Server and Tools. For Q3 and the full year, we expect non-annuity revenue, approximately 30% of the total, to generally track with the hardware market. Multi-year licensing revenue which is about 50% of the total, and enterprise services, the remaining 20%, should grow high-single digits for the third quarter and low double-digits for the full fiscal year.

This suggests that 80% of the revenue is from licensing and that 20% is “enterprise services” – which as I understand it is the consulting and enterprise support division at Microsoft. So where is Azure?

Online services, which is Bing and advertising, announced another set of dismal results. Another part of Microsoft’s cloud, Exchange and SharePoint online, is lost somewhere in the Business segment. Overall it is hard to judge how well the company’s cloud computing products are performing, but I think it is safe to assume that revenue is tiny relative to the old Windows and Office stalwarts.

Windows Phone 7 gets a mention:

While we are encouraged by the early progress, we realize we still have a lot of work ahead of us, and we remain focused and committed to the long-term success of Windows Phone 7.

It looks like revenue here is tiny as well; and like most corporate assertions of commitment, this is a reflection of the doubts around Microsoft’s mobile strategy overall: how much of it is Windows Phone 7, and how much a future version of full Windows running on ARM system-on-a-chip packages?

Still, these are good figures overall and show how commentators such as myself tend to neglect the continuing demand for Windows and Office when obsessing about a future which we think will be dominated by cloud plus mobile.

Talk of Windows 8 on an smartphone shows Microsoft’s mobile confusion

During a conference call to discuss Intel’s latest financials, CEO Paul Otellini raised the possibility of putting the full Windows OS onto a smartphone, running a low power Intel SoC (System on Chip). The matter came up with Otellini was asked about the impact of Windows on ARM, announced at CES earlier this month:

The plus for Intel is that as they unify their operating systems we now have the ability for the first time: one, to have a designed-from-scratch, touch-enabled operating system for tablets that runs on Intel that we don’t have today. And secondly, we have the ability to put our lowest-power Intel processors running Windows 8 – or ‘next-generation Windows’ – into phones, because it’s the same OS stack. And I look at that as an upside opportunity for us.

The reasoning seems to be: if Windows 8 is designed to run well on mobile devices with ARM, it will also run well on mobile devices with an Intel SoC, which will let us put it on phones.

Note the point he highlighted: Microsoft unifying its operating systems. No more full Windows vs Windows CE; one OS from mobile to desktop.

Although that sounds compelling, the snag is that Windows is not well suited to low-power mobile devices, which is why Windows CE was invented in the first place. Microsoft can fix this to some extent by fixing the things that make it unsuitable, but it carries a heavy compatibility burden.

It also throws up the question: just what are Microsoft’s long-term plans for Windows Phone 7, which is built on Windows CE, has its own GUI mostly written in native code, and a development platform based on .NET – Silverlight and XNA – plus a native code SDK that only mobile operators and device manufacturers get to use?

At CES Microsoft Steven Sinofsky sort-of denied that Windows will encroach on Windows Phone 7 territory. “Windows Phone 7 is uniquely focused on the small form factor that Windows doesn’t focus on,” he said.

Nevertheless, the company’s decision not to use the Windows Phone 7 OS for tablets may make that inevitable. What is the difference between a smartphone and a small tablet? Does Microsoft expect developers to write apps designed for Windows on a small tablet and then rewrite them for Windows Phone 7 using Silverlight?

It does not make sense; and despite the Windows Phone 7 promotion included in CEO Steve Ballmer’s CES keynote, I was left wondering whether Microsoft’s new mobile OS really has a future.

That said, Silverlight abstracts the OS, so in principle Microsoft could use it to form a consistent mobile development platform irrespective of whether the underlying OS is Windows CE or full Windows. I am not getting that sense from the company though, and I’d expect the primary Windows SDK to remain based on C++.

I am struggling to understand how Microsoft expects this to work. App compatibility is the obvious benefit of full Windows; but two big issues are that most Windows apps are not touch-friendly and are not designed for small screens. Putting Windows on a tablet with a decent screen size and the dreaded stylus works to some extent, but will never compete with Apple’s iPad for usability. On smaller screens most existing apps will not work properly; and if Windows on small devices sprouts a completely new touch-friendly GUI, or borrows the one from Windows Phone 7, then app compatibility with desktop Windows will be limited.

It feels as if Microsoft’s Windows team is saying one thing, the Windows Phone 7 and developer teams saying another, and partners like Intel saying yet another. Windows Phone 7 was meant to be the thing that made belated sense of Microsoft’s mobile strategy, but even that now looks doubtful for the reasons stated above.

Microsoft is still a long way from having a coherent strategy for mobile devices, and that lack is damaging the company and helping Apple and Google to establish their competing operating systems.

Update: Mary-Jo Foley writes about Microsoft “Jupiter” which is a rumoured new user interface and application model designed for Windows 8 and its app store:

Jupiter is going to be a new user interface (UI) library for Windows, built alongside Windows 8. It will be a thin XAML/UI layer on top of Windows application programming interfaces and frameworks for subsystems like graphics, text and input. The idea is Jupiter will bring support for smoother and more fluid animation, rich typography, and new media capabilities to Windows 8 devices.

Is Jupiter a .Net technology, or XAML adapted for native code, or both? Is it one and the same as, say, Silverlight 6? That is not stated, though Senior VP Soma Somasegar helpfully (or not) said that:

some of the information in this post is not right and out of date, not reflecting Microsoft’s current thinking.

That seems to tacitly confirm that it fairly represents Microsoft’s thinking at some time in the not-too-distant past.

It would make sense to me if Microsoft used Silverlight to unify its application platform as mentioned above, and combining the XAML presentation layer with native code could address performance and memory usage concerns with .NET. This is the kind of news that would really give confidence to Silverlight developers, rather than the damage limitation PR that Microsoft has put out since PDC late last year.

On the other hand, I believe Somasegar when he says the information is out of date, so for the time being it is just another dose of uncertainty.

Microsoft WebMatrix released: a simple editor for ASP.NET Razor and more, but who is the target user?

Microsoft has released WebMatrix, a free tool for creating web sites for Microsoft’s web server. It uses the Web Platform Installer and installed smoothly on my Windows 7 64-bit box. What you get is a cleanly-designed tool which lets you start web sites from templates or from standard installs of popular applications including WordPress, Drupal and Moodle.

image

Yes, you can use PHP and MySQL as well as .NET web applications, though the common factor is that all are configured for IIS, Microsoft’s web server.

With many ISPs already offering instant installs of apps like WordPress, it is more interesting to look at the site templates in WebMatrix, though the selection is smaller.

image

What is interesting about these is that they create sites based on Razor, an alternative view engine for ASP.NET. Microsoft VP Scott Guthrie describes Razor here. It is odd though: Razor is a feature of ASP.NET MVC 3, currently in release candidate phase, but you cannot create ASP.NET MVC sites in Web Matrix.

Once a site is created, you can modify it in the WebMatrix editor.

image

You can run the site on IIS Express with one click. WebMatrix will show you all the requests as you run, which could be handy for tracing problems. There is also a database management workspace which uses SQL Server Compact Edition, a reporting workspace which will analyse your site for problems, and the ability to publish a site using  FTP or Microsoft’s Web Deploy.

I like the clean look of WebMatrix, and that it is lightweight and fast; but who is the target user? It appears to be aimed at non-professionals; but this is a techie product that will not appeal to users looking for an easy to use web site builder. There is no visual editor; users are just chucked in at the deep end editing raw HTML and C#. There is not even any intellisense code completion. Clicking Online Help just brings up a Microsoft search form. There is no debugger to speak of; you are expected to upgrade to Visual Studio. Which raises the question, why not just get Visual Web Developer 2010 Express, which is also free, and has a better editor and debugging features? Of course you could use the two together; but Web Matrix is not adding much value. Features like the SEO analysis seem to be be based on the existing Search Engine Optimization Toolkit, which you can install without Web Matrix.

WebMatrix has been available in beta for six months, but its forum is relatively quiet.

Still, if nothing else Web Matrix is a handy way to take a look at Razor, which deserves attention. Shay Friedman has a technical introduction here.

Guthrie has a detailed look at the WebMatrix beta here.

Apple’s Mac App Store – and the forgotten Windows Marketplace

Apple launched the Mac App Store yesterday and I had a look this morning. It is only available to users of Mac OS X Snow Leopard, where it comes with the latest system update.

image

It is interesting that Apple has not used iTunes for the App Store, but has developed new client software. Maybe it is coming round to opinion that iTunes has become bloated; it is only for historic reasons that a music player has become an all-purpose app installer.

The store itself worked well for me. I picked a free app, TextWrangler, and signed in with my Apple ID. The UI showed Installing, then Installed, and I was done.

image

The TextWrangler icon appeared in the Dock so I could start the app easily.

What counts is what I did not have to do – reboot, select from setup options, or deal with perplexing error messages.

Users will also like the common-sense licensing, which lets you download and install a purchased app on any Mac you use, controlled by your App Store log-in. I am not sure what happens if you install your app on your friend’s Mac, then sign out of the App Store. There is some link between the app and your Apple ID, because if you copy the application to another Mac it will ask for your sign-in details when you first run it, but I am not clear whether this is checked on every run to deter piracy.

Most important, there is an attractive range of apps at good prices. In the UK, Angry Birds is £2.99, Pinball HD £1.79, and Apple Pages or Keynote £11.99 each. That is less than typical Apple Store shrink-wrap prices. The prices for Pages and Keynote makes the price Microsoft charges for Office look impossibly expensive. Good for customers; but worrying for independent software vendors who want to make a living.

Developers pay $99.00 per year to join the Mac Developer Program and then 30% commission to Apple on every sale. Of course, like the iPhone App Store, apps are subject to Apple’s approval.

Lest you think it is clever of Apple to invent an app store for the desktop, it is worth noting that the concept is an old one. Linux has delivered free software like this for years, and some distributions have also featured paid app installers integrated into the OS.

So has Microsoft, which has run various varieties of Windows Marketplace over the years, for mobile and desktop applications. Windows Vista shipped with an app store for both Microsoft and third-party apps built-in. It was on the Start menu:

image

as well as in Control Panel:

image

On November 1st 2008 Microsoft shut down Windows Marketplace and “transitioned” it to a referral site. There was some angst at the time about the closing of the digital locker, which proved insecure against the threat of corporate mind-changing. It still runs the online Microsoft Store, but this is for Microsoft-only products. For example, you can download Microsoft Songsmith for £25.00:

image

Why did Windows Marketplace fail? Well, the user experience was poor, it was insufficiently prominent in the Vista user interface, setup could be troublesome. Major Windows app vendors figured out that they would be better off drawing potential customers to their own web sites, where they have full control. As is often the case, Microsoft was conflicted over whether it wanted to drive customers to the online store, or to partner retailers, or to app vendor sites; and the OEMs would have their say as well, when customising Windows for their own PCs.

Another factor is that Windows apps are often not well isolated. Silverlight actually solves this problem – out-of-browser apps are well isolated and secure – but Microsoft does not even ship Silverlight by default with Windows.

The indications are that Microsoft will have another go in Windows 8. Documents leaked last year show an app store. From my post at the time:

There’s a pattern here. Microsoft gets bright idea – Tablet, Windows Marketplace, Passport. Does half-baked implementation which flops. Apple or Google works out how to do it right. Microsoft copies them.

NVIDIA’s first CPU, Project Denver, aims to bring ARM to desktops and servers

At CES in Las Vegas today NVIDIA’s CEO Jen-Hsun Huang announced the company’s first CPU: Project Denver. This is a partnership with ARM, to create “a full custom processor” targeting “high performance computing – servers, PCs, super-computers, cloud computing.” NVIDIA will still licence ARM processors for mobile computing.

Since ARM has in the past focused on the mobile and embedded market, and NVIDIA on GPUs, it is a departure for both companies.

Why? Huang says it is because ARM is “the new standard microprocessor architecture.” Judging by this chart, shown at the press briefing, it is hard to disagree:

image

In a few years, said Huang, “There will be more ARM processors shipped than all the x86 chips ever shipped.”

image

NVIDIA’s press release explains that the purpose of Project Denver is to extend the range of ARM systems upwards:

For several years, makers of high-end computing platforms have had no choice about instruction-set architecture.  The only option was the x86 instruction set with variable-length instructions, a small register set, and other features that interfered with modern compiler optimizations, required a larger area for instruction decoding, and substantially reduced energy efficiency.

Denver provides a choice.   System builders can now choose a high-performance processor based on a RISC instruction set with modern features such as fixed-width instructions, predication, and a large general register file.   These features enable advanced compiler techniques and simplify implementation, ultimately leading to higher performance and a more energy-efficient processor.

The other interesting aspect of Project Denver is its integration with the GPU – as you would expect from NVIDIA:

An ARM processor coupled with an NVIDIA GPU represents the computing platform of the future.  A high-performance CPU with a standard instruction set will run the serial parts of applications and provide compatibility while a highly-parallel, highly-efficient GPU will run the parallel portions of programs.

While we tend to focus most on power efficiency for mobile devices, because we notice how long our batteries last, it is equally important for larger systems. Power consumption and dealing with heat is a key issue for datacentres, while in everyday desktop computing power consumption is a significant proportion of the running cost of an IT system.

Project Denver puts a different spin on Microsoft’s Windows-on-ARM announcement today. The assumption is that Microsoft has in mind a mobile future for Windows; but if Denver takes off it could be important on desktops and servers as well.

Before getting too excited, it is worth recalling how Intel’s Itanium, cruelly dubbed the Itanic, mostly failed in the market. That was partly thanks to design problems, and partly because the industry was too deeply hooked into x86 applications. I also recall Motorola’s doomed attempts to sell Windows NT on PowerPC in the mid Nineties.

Denver could fare better, thanks to the ubiquity of ARM in the mobile world. That said, much will depend on whether a Denver-based system really does offer significant benefits over whatever Intel and/or AMD will have come up with by the time it ships. If it is less than spectacular, Denver will be a hard sell.

Windows 8 will run on ARM processors – a natural home for Silverlight?

Microsoft announced today at CES in Las Vegas that the next version of Windows will run on ARM as well as Intel CPUs. But why? The reason is that ARM CPUs have huge momentum in mobile computing, thanks to their low power consumption. Microsoft wants Windows to support System on a Chip (SoC) architectures such as NVIDIA’s Tegra 2, which has two ARM Cortex-A9 CPUs combined with an HD-capable graphics processor in a single package. In its press release, the company is careful not to upset established x86/x64 partners Intel and AMD too much, emphasising that Windows will run on SoC packages based on those CPUs as well.

It is an interesting announcement, but one that raises as many questions as answers. The first concerns Microsoft’s mobile strategy, with Windows now seeming to encroach on territory that you have thought belonged to its embedded operating system, Windows CE, which underlies both Windows Mobile and Windows Phone 7. With all its legacy APIs, full-blown Windows does not seem ideal for low-powered, resource-constrained mobile devices; yet the company seems set on bringing full Windows rather than something based on Windows Phone 7 to the emerging tablet market.

The second issue is that applications will need at least re-compiling, and in many cases some re-coding, in order to run on ARM CPUs. Microsoft says it will deliver Office for ARM:

Sinofsky: Microsoft Office is an important part of customers’ PC experience and ensuring it runs natively on ARM is a natural extension of our Windows commitment to SoC architectures.

Windows and Office alone is enough for a decent business device; but customers who buy Windows on ARM expecting their existing games or applications to run will be disappointed.

We have been here before. In the early days of Windows CE, devices ran a variety of processors such as MIPS or Hitachi SH3, and developers had to compile multiple binaries and create setups that installed the right one on each device. In an attempt to overcome the friction this created, Microsoft introduced the Common Executable Format (CEF) with Windows CE 3.0 in 2000. This was an intermediate language format which was translated to native code by a “translator” when it was installed onto a device.

It sounds  a bit like .NET or Java; and it was indeed a forerunner of the .NET Common Language Runtime, which appeared in 2002. However, CEF never really caught on. Although it solved deployment issues, it introduced performance problems and was troublesome to debug. Most developers preferred to stick with true native code.

Today though .NET is mature; and we also have Silverlight, a cross-platform implementation of the .NET Framework combined with multimedia player and graphics framework. If Microsoft includes .NET and Silverlight in its ARM build of Windows, that would solve some of the deployment problems, especially for business devices. Many custom applications are built for .NET; and these would in principle run without any need to recompile, since a .NET executable is intermediate code which is compiled to native code at runtime, though any code which includes “platform invoke” calls to native APIs would not work.

It is surprising therefore that neither .NET nor Silverlight is mentioned in Windows president Steve Sinofsky’s Q&A about Windows on ARM. Still, we should not read too much into that. It would be madness if Microsoft did not support its .NET technologies on this new platform, would it not?
