MSDN Nuggets has a bunch of short videos (similar to hte great 10 minute groktalks) on how to do a variety of things in .net.

I caught this one by Mike Taulty that is on hosting windows forms controls in asp.net. What I really liked is the way he demonstrated the code access security issues that you have to be aware of. Rather than saying "don't do this", he did do it and showed what happens. Nice.

Follow the above link and look for "Hosting a WinForms Control on an ASP.NET web page".

One thing that really surprised me was seeing Mike's email on the beginning of the video. I had no idea he worked for Microsoft!
