Download Sample Code MVVM Playground Have I mentioned lately that I love the MVVM presentation pattern?? If I haven’t please allow me to do so now. It makes unit testing much much easier, the clean separation between logic and presentation makes me feel all warm on the inside, and (Blendability) those designers in the black turtle necks can run off and build an awesome UI in XAML while us devs write our code in peace :) Ahhh, so ok there are some issues that we are going to run into in the MVVM space....
