On Saturday, November 7, 2009 at 9:00am I presented at the Desert Code Camp in Phoenix, AZ. The topic of my presentation was Silverlight casual game development. In less than an hour I demonstrated how to use triggers, actions, and behaviors in Blend 3 to create a hidden object game. Because all code was contained in the TABs (Triggers, Actions, and Behaviors) there was no code behind for the main UserControl.
Here is a link to the presentation video in WMV format.
If you like you can see all the episodes and follow along with the tutorial.

Fantastic post, where is the souce code link?

Missing references, where can I get them?
The type or namespace name ‘Expression’ could not be found (are you missing a using directive or an assembly reference?)
