VisionWorks -- WIndows 7

I would like to use the windows version of VisionWorks and downloaded the windows beta version and when I was at GTC I asked whether I needed Windows 8 or would it work with Windows 7 and one of the NVIDIA folks said that it works with Windows 7 which is what I have. The installation instructions says to use Visual Studio 2013. Is there a specific reason 2013 is mentioned or would 2015 also work?

Right now the CUDA toolkit (7.5) lists VS 2013 as officially supported. VS2015 is not an officially supported development environment for CUDA 7.5
