This year biggest event on Microsoft technologies, DevDays 2007, is already open. You can go and subscribe now. I have two sessions there:

Best practices using TFS Source Control and Team Build

Analysis and Tuning of WCF Applications

The major difference in this year event is that it has a small registration fee. You can read more here. Also the list of sessions is pretty impressive.
This is definitely a step in the right direction from Microsoft Bulgaria.

See you on 10-11 May 2007 at Hilton Hotel.
