I forgot to mention Databinding

In my last post about XAML I forgot to mention data binding. It appears to have improved a lot. From the demo i saw, you can now bind more than one object to the same data source and they both get updated "automagically" when the data changes.

This really kicks arse IMHO. Its like you get a Model View pattern now without having to implement the Observer pattern.

Damian Edwards who did the presentation had used it to make a demo game of Space Invaders using a timer and data binding. Very cool.
