Karsten just posted 3 more days of intense WPF Boot Camp training at MIX University
. This is our most updated training, delivered recently here in Redmond by several experts from Microsoft and our partners. It takes you from beginner to intermediate in the first two days, and then dives deep into some real-world implementations on day 3.
