The official Kinect SDK is here, so there shouldn’t be any problems with incompatible frameworks and libraries on Windows systems. That being said, there are already a couple of interesting resources that I would say are important for developers who just start Kinect development, and for those that were already working with it (e.g. with OpenNI or OpenKinect).
