I recently attended a Microsoft MSDN Roadshow. The slides for the presentations are here:
* ADO.NEXT – Entity Framework & Data Services
* ASP.NEXT – The ASP.NET 3.5 Extensions
* Building Rich Internet UI with Silverlight 2
* Getting the most from the Visual Studio Team Suite Toolbox
Probably the most interesting area was all the tools that are now available in Visual Studio Team System for unit testing, SQL refactoring and schema versioning.
