In the latest edition of MSDN TV, Don Box and Chris Anderson give new meaning to building mission critical apps :-). In this episode, "Special Holiday Episode III: Connecting People, Programs and Devices Using WinFX" they have fun geeking out with WinFX at Don's house. You might want to turn the volume down towards the end when they start to sing :-)

Enjoy and Happy Holidays!
