I have been on the Visual Studio Launch Tour visiting Chicago, Des Moines, Madison, Omaha, Kansas City and St. Louis over the last couple months. As part of that we've been showing new features of Visual Studio for web development.
I've uploaded the sample web site code from the Visual Studio Launch events onto http://www.benkoTips.com/code. This includes the examples showing style sheets, LINQ and Ajax. If you were able to join me at the launch you've seen the demos, but I'm also working on some screencasts of these which registered users can view by clicking in the link below (note that you will need to have Silverlight installed to view the demos).
