Microsoft’s “On-Demand Webcasts” are a great resource. Microsoft archives their live webcasts and makes them available for free via MSDN. I encourage everyone to have a look around.

1. Advanced .NET Programming for Grid Computing Dan Ciruli from DigiPede reviews grid computing, largely in the context of their product.
2. Windows Presentation Foundation Properties, Events, and Commands - covers Dependency Properties, Events, Commands
3. Amazing but True: Things You Never Dreamed You Could Do with Windows PowerShell - quite strange really, and the rendition of the Notre Dame fight song made me puke (Go Blue!) but if you sit through about 5 minutes of goofiness you learn some cool Powershell stuff.
4. Client-Centric Programming Using the “Atlas” Client Script Library - Digs into the Atlas Client Script Library, covering some of the lesser-known corners and advanced techniques in Atlas. Cool!
5. Java Interoperability with .NET

Plus two bonus webcasts - Top 10 Tips for Word 2007 and Top 10 Tips for Excel 2007. I don’t know about you, but I find that Office 2007 is a major departure from the earlier versions and I am still getting up to speed. As with most of the links above, the first 5 minutes or so tends to be a bit fluffy but then it provides some great red meat.
