Here is the code the goes along with my January 25 presentation titled "Augmented Reality with the Kinect" at the Lincoln .NET Users Group.
Remember to check the https://www.microsoft.com/en-us/kinectforwindows/ Kinect for Windows site to verify you have all of the system requirements.
To get started with basic Kinect for Windows coding, I recommend Microsoft's Skeleton Sample.
The Kinect with WPF (Video Magic WPF) sample code from my presentation is available for download at https://graxark.codeplex.com/releases/view/81378.
The Kinect with XNA sample code will be posted soon. I am doing a bit of cleanup to remove unused code and such before posting.
Feel free to ask questions. I will answer them if I can.
