Since so many people mentioned MVC in my post asking about future updates that you are most looking forward to (here), I thought I would post some helpful information around MVC.
Of course, Scott's blog has some great information on it - here.
There is a great set of online videos found at An Introduction to ASP.NET MVC using VB.
And of course there is lots of useful information on the http://www.asp.net/mvc/ site and the wiki on there at http://wiki.asp.net/page.aspx/286/aspnet-mvc-framework/.
For a great example using MVC, check out this blog for a walk-through e-commerce store with full application lifecycle including agile and TDD design.:
