Tutorial on how to build a WPF application in Visual Studio 2010 using C# and the Microsoft Kinect SDK v1 to stream the RGB depth video source and the skeleton tracking source. The Kinect SDK can be found at the following link.

The following video tutorial shows how to implement wpf kinect skeleton tracking viewer.
