I followed the link to getting the latest pre-release, but I'm unfortunately still unable to bring in the NuGet package. I've included a screenshot with the Output log to show you what I'm getting.
I'm using MonoGame 3.5.
I open Visual Studio Community 2015, select New Project...
I select MonoGame > MonoGame Windows 10 Universal Project
Under the New Universal Windows Project dialog I choose:
Target Version: Windows 10 Anniversary Edition (10.0; Build 14393)
Minimum Version: Windows 10 (10.0; Build 10586)
