Microsoft's Mike Harsh just released an updated version of his WPF/E Pad that makes it easy to quickly test out XAML using the WPF/E viewer.  Pretty cool stuff!  Since I'm a big fan of XML I'm really excited about what WPF/E offers.

My good buddy Simon Allardice (who also works at Interface Technical Training) has posted several cool demos on using WPF/E at the following links as well:

• Count-Down Timer
• Mouse Tracker
