Brad Wilson of the Microsoft ASP.NET MVC Team presented Advanced ASP.NET MVC 2 at the Seattle Code Camp. You can watch the video here, but be forewarned that the screen was unfortunately cropped. Still, the content was excellent and one can still get a lot of value from the video.
You can also download the slides and code from the Advanced ASP.NET MVC 2 Presentation. Check out Brad Wilson's post for more information.
If you are interested in ASP.NET MVC 2 and live in the Sarasota, Florida area, we are learning ASP.NET MVC from scratch at the Sarasota Web Developer Group.
If you are looking to buy an ASP.NET MVC Book, you can review several ASP.NET MVC Book Reviews.
