I've been looking for the same. Haven't had much luck. Microsoft offers documentation as msdn.com for the VB.NET language, which is one language which can be used with ASP.NET. They also offer some tutorials at ASP.NET about ASP.NET in general and also ASP.NET as it relates to their free web development tool, Web Matrix. I found the Web Matrix tutorial easier to understand than the general ASP.NET tutorial. There is also a site:
http://authors.aspalliance.com/aspxtreme/ that offers a lot of information on ASP.NET. I think what is really lacking is example driven learning.
Respectfully,
David.
