NLog.Extensions.Logging: Can't install on .NET 4.6.1 - System.Runtime not found in the GAC

I can’t install NLog.Extensions.Logging 1.0.0-rtm-beta1 in a .NET 4.6.1 console application. It fails with this error:

Failed to add reference. The package ‘NLog.Extensions.Logging’ tried to add a framework reference to ‘System.Runtime’ which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for assistance.

Sounds similar to #52.

Steps to reproduce:

1. Create a new C# console application for .NET 4.6.1
2. Run Install-Package NLog.Extensions.Logging -Pre

Here’s the entire install log:
