Visual Studio Orcas Beta 1 was release last week and it fully supports LINQ. However the ADO.NET Entity Framework has been cut from Orcas.
LINQ to SQL and the designer will be included. News on Frans Bouma's blog.
Scott Guthrie in his Channel9 interview on Silverlight said that Silverlight will support LINQ ... getting the SDK now to try it out.
Here's a screen shot of silverlight and some code in the background in Orcas - the code and a screencast is available on Channel9:
Years ago, before Mozilla took off and developed XUL, and XML was still new and began generating a lot of buzz, there was some question about the ultimate platform that we'd end up on, and XML was the foundation of it all. Everyone thought so at the time. I was involved in a project called XPL - XML Programming Language, the intention of which was to provide a base dialect for languages and a runtime - a Common Language Runtime. When the CLR was announce, and IL came out and I saw Visual Basic.NET and C# and JScript.Net I figured this would be what Microsoft would do -> Silverlight.
Not that I knew how they'd go about doing it, but I wrote an email to my cousin years ago saying Microsoft would dominate the browser again via XML as the interface language, instead of HTML, but by leveraging a dialect that they can create that merges the Windows Desktop with the Web. XAML.
There is little doubt in many people's minds, I am sure, that Microsoft planned this long ago, but lest the Mozilla/Firefox/XUL guys come claiming to have thought of it first: you didn't. You just did it first. Microsoft has been planning this since XML and the CLR were coined I think, and JScript.NET is the first case in point.
Introduction to F# Programming Part 2 with Don Syme. Incredible demo of concise and interactive DirectX 3D programming.
Very good introduction to BI and Microsoft SQL Server 2005 features. Highly recommended.
