Microsoft Kinect SDK is claimed to work under Windows 8.
Well, before you run-off starting to develop your next Kinect multi-touch experience for the Windows 8 UI, it is important that you know that there are limitations to that.
Although using the latest Kinect SDK driver, released October 2012, you can develop and run apps under the Windows 8 operating system, it only works for developing traditional desktop apps, meaning what you would call “Windows 7 apps” and not what is called: “Windows Store apps”, also formerly known as “Metro-style apps”.
The Kinect libraries are not compatible with Windows Store apps and therefore you cannot add a reference to a legacy library that works against the Kinect SDK. Visual Studio 2012 prompts you with an error message saying: “Unable to add reference”.
I’m currently working on a work-around that may enable a small portion of the Kinect features in Windows Store apps and will surely update when I come-up with something.
