Last week I participated in the Microsoft .NET Techology Briefing in Milwaukee. I gave a presentation on what's new since .NET 2.0. Topics included .NET Framework 3.0 and 3.5, ASP.NET AJAX, Silverlight, and Visual Studio 2008.

Simple demo projects I created in Visual Studio 2008 (LINQ to SQL demo won't have the database so it won't run)
