Visual Studio - Missing "GameAssembly.lib"

I have built a UWP project out of Unity, and have opened the solution in Visual Studio. After trying to build it, I get two errors:

I looked in the directory listed for GameAssembly.lib, and the file doesn’t even exist. I tried downloading the 2015 build tools, and the errors still came up. Is there a way to get this file, or a way to create it?

I used Unity 2017.2.0f2 Beta personal (64-bit) and I also need the file GameAssembly.lib. I also get the warning that SuppressSystemOverlays::set has been marked as deprecated in Visual Studio 2017. Any help would be appreciated.
