Grovepi, Windows IoT, C++



Is there anyone who has some experience starting up Grovepi with Windows IoT in C++? I have found the package of cpp in Github, but I guess it is for Rapbian jessie. I copied them in my project, but when compiling there is even missing header file (e.g. unistd.h) in grovepi.h. I also found some demo for Grovepi with Windows IoT but they are in C#. Now I want to use the VS to write the code and use the benefit of Windows IoT to develop my Grovepi, but in C++ as required by the whole project. So is there any advice on how to start up/transplant/configure? Thanks in advance.
