Silverlight 4 ticks all the boxes, questions remain

6 Comments

Microsoft has announced Silverlight 4 here at PDC in Los Angeles. The gist of it I was expecting – device support, an option for fuller system access out of the browser – but the extent of the new features is remarkable. Here’s a few highlights:

  • Improved Just-in-time compilation gives 30% faster start-up, up to 100% performance increase
  • COM automation support on Windows when out of browser with full trust
  • Access to local file system, cross-site Internet access, custom window chrome when in full trust out of browser
  • Notification pop-up support even when sandboxed
  • Drag and drop target even when sandboxed
  • HTML control (only works out of browser), supports plug-ins
  • Rich text control with right-to-left text support
  • Printing support
  • Clipboard, right-click and mouse wheel support
  • Web cam and microphone support

Of course there are a few unanswered questions, such as what level of HTML support is available, or how Microsoft is protecting users from malicious Silverlight applets; I’ll be exploring these later today.

It’s clear though that Microsoft wants to compete fully with Adobe AIR, and that its energetic Silverlight development is continuing at full pace.

The beta is available now; full release is promised for the first half of 2010.

So where is Microsoft going with this? Why would anyone develop for WPF and Windows, if good enough features, cross-platform, and zero install is available through Silverlight?

Interesting times for .NET developers.

PDC day one: Windows in the cloud

Today was cloud day at PDC. Microsoft announced that Windows Azure will become a production platform on January 1st, with billing starting from February 1st. It also announced the beta of Windows Server AppFabric role, for on-premise apps that can either stay on-premise or be deployed to Azure later; and some new developments like the Windows Server Virtual Machine role on Azure, a pre-configured Windows Server VM into which you will be able to deploy an application.

Azure was first announced at the 2008 PDC, and had a stuttering start, with a CTP (Community Tech Preview) that was difficult to use, major changes to SQL Server Data Services – a simplified cloud database that was scrapped and replaced with full SQL Server – and generally poor marketing from Microsoft. I was not sure whether the company was serious about Azure, or merely trying to tick the cloud box.

I do now think it is serious, and delivering some interesting technology for easily scalable cloud-hosted applications. Microsoft does not sees its cloud services as replacing your in-house servers (no surprise there), but more as a way of deploying certain kinds of web applications. A great feature is that thanks to Active Directory Federation Services in combination with the new .NET library called Windows Identity Foundation you can relatively easily have use your Azure applications authenticated against your internal Active Directory.

The surprise of the day was when Matt Mullenweg of WordPress fame turned up to demo WordPress running on Azure, which now supports PHP and MySQL as well as Java applications. Another unexpected guest was Loic Le Meur of Seesmic, who introduced Seesmic for Windows and also talked about a coming Silverlight version.

That said, the keynote did not exactly crackle with excitement. Microsoft seemed almost to downplay what is now possible with Azure, perhaps sensing that it could be disruptive to its own business model. A telling moment came during a press briefing when Doug Hauger, Azure General Manager, denied that Windows or Office were in any sort of decline. Despite his position he seems to be under the illusion that we will happily continue with our fragile on-premise, single platform, micro-managed IT systems.

I enjoyed the day though. The beauty of PDC is that Microsoft rolls out its best speakers; it was great to hear Mark Russinovich explain the kernel changes in Windows 7 and Server 2008 R2 – same kernel of course – and I will be writing more about the session shortly.

I’m expecting more focus on Office, Silverlight and Visual Studio tomorrow, when Steven Sinofsky, Scott Guthrie and Kurt DelBene will be giving the keynote, and hoping for some compelling announcements.
