Visual Studio 2015: Type universe cannot resolve assembly: System.Runtime, Version=0.0.0.0

Question

I am encountering a problem with Visual Studio when trying to design UWP Forms. The designer doesn\'t load, all I\'m getting is this error:

Microsoft.Metadat         


        

Answer 1

I was able to resolve a similar error by checking "Automatically check for missing packages during build in Visual Studio" (the "Allow NuGet to download missing packages" was already checked), then rebuilding. You can find these settings in Tools --> NuGet Package Manager --> Package Manager Settings.
