I have a Visual Studio C# WPF Windows 7 application and have been searching for way to create a avatar.  With the release of Windows Kinect SDK this would be an amazing pairing.  The XNA/Game Studio 4 provides the perfect Avatar creation library (http://msdn.microsoft.com/en-us/library/dd940289.aspx).  While this XNA library compiles in Windows the Avatar can only be displayed from an XBox.

Is there a simple/powerful approach or library for creating/controlling a windows 7 avatar for use with Kinect SDK?  I would be open to using XNA or DirectX, although I believe DirectX has a steep learning curve..
