Failed to add reference to 'System.Runtime'.

[isaaclyman]

When I try to install KickStart and KickStart.Unity from NuGet package manager, I get the error:

Failed to add reference to 'System.Runtime'. Please make sure that it is in the Global Assembly Cache.

As a workaround, I manually click "Add Reference" for the References in each project and add a reference to the following file:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\Facades\System.Runtime.dll

Then I can install the packages without issues. However, Visual Studio provides the following warning:

The referenced component 'System.Runtime' could not be found.

I feel that something is amiss here. However, KickStart seems to be running fine.

I don't see this issue with my test project.
