Want to learn more about Windows Vista and Office 2007 development?
We're hosting some of these dev events in various cities, and you could win a Zune just by registering for one of 'em.
And since we're talking about free events, I'll also mention the MSDN Events, the ASP.NET 2.0 Training, and the MSDN Events Online Webcast Portal. Of course, I have to mention my webcast series on Visual Basic Soup to Nuts, too. :)
Then again, there are a ton of free training opportunities on the web.
What are your favorite links to training?
