Edited Unassigned: Please remove the XNA stuff and update the library to target .net core (UWP). [21]

This is unusable for Windows store apps as it is. I'm going to look at the source to see if i can do something with it. Hopefully i can just build a new solution. But we'll see. UWP uses .NET core instead of .NET framework.

XNA ?? Why use something so old, no one uses XNA anymore. There's only so many times i can reinstall something that I'm never going to use. Look at building a SharpDX sample.
