You may notice that there is no neither .NET no UWP support on OpenCV site. I think that is because Microsoft has to do something with this.
For people it is obvious that https://github.com/Microsoft/OpenCV repository should contain everything required to use the latest OpenCV from supported by Microsoft projects. However now it looks like abandoned repository.
Microsoft should regularly update the latest OpenCV source code.
You should keep all code updated to the latest Visual Studio and Latest SDK (how it is VS2017 and UWP Full Creators Update).
You must provide people nuggets with precompiled x86, x64 and ARM binaries for UWP.
Microsoft it is your duty because the name of this repository is https://github.com/Microsoft/opencv/
