Excellent Silverlight/WPF MVVM video series
Here's an excellent video series on Silverlight/WPF (XAML basically) and the MVVM pattern.
He does, what I believe to be, an excellent job of covering XAML and MVVM during this series, and includes a bit of unit testing as well.
Part one is included below, but another user on YouTube created a Playlist with the eight videos released.
Update: Or you can view his blog post, time cockpit at NRWConf.
