MSDN TV
I'm sure most of the .NET developers who read my weblog will already know of MSDN TV but this post is more to those who haven't caught on yet. MSDN TV is a twice-weekly short (around 10mins) video on tips regarding .NET. The current episode by Doug Purdy on .NET Remoting is a killer!
Don't forget to check out Microsoft Insider, current episode is on Tablet PCs.
