My teammate, Rob Cameron, runs a regular webcast series called .NET Developer Update (.NDU) that covers technologies that .NET developers are interested in.
I'll be doing a webcast on Visual Studio 2008 2008 Team Suite Database Edition on Friday, May 23. The webcast is from 11 AM to 12:30 PM PT.
If you're not familiar with this edition, it provides advanced tools for database change management and testing and offers functionality to enable database developers and administrators to be more productive and increase application quality in the database tier.
All .NDU webcasts are recorded, so if you can't catch the webcast live, you can always view it later. I'll post the link to recorded session when its made available.
