Someone asked me recently for a list of webcasts/video presentations on ASP.NET 2.0. In looking to answer his question I stumbled upon a link that I didn't know existed: http://msdn.microsoft.com/asp.net/reference/multimedia/ It has about 15 videos of using ASP.NET 2.0 and VS 2005/Visual Web Developer (including a webcast by me).
Update: Here is another really great site full of .NET videos to check-out: http://lvstechie.web1000.com. It has free online ASP.NET 2.0 presentations from a whole bunch of sources. Definitely worth checking out.
Hope this helps,
P.S. We have a number of videos we are working on that we will be uploading soon to http://www.asp.net. So a lot more are coming.
