Lots of good quality MSDN shows for your viewing pleasure:
- Scott Guthrie on Data with ASP.NET in Visual Studio 2005
- Pablo Castro provides a First Look at ADO.NET 2.0
- Krzysztof Cwalina on the new Generic APIs in the .NET Framework 2.0
Footnote: For those of you paying close attention, these used to be part of the “Whidbey Chronicles” MSDN series, but since VS 2005 was officially announced, we're not supposed to use “Whidbey” anymore, in fact we changed the old shows to be “Visual Studio 2005”).
