Fody mscorlib not found on .NETStandard project

See original GitHub issue

Hello,

I am using Fody with AsyncErrorHandler.Fody and PropertyChanged.Fody in a PCL project which targets .NETStandard1.1.

When building I get the error that Fody cannot find mscorlib. Here the full stack trace: 1>FodyTarget: 1> Fody: Fody (version 1.29.4.0) Executing 1> Fody: ProjectDirectory: 'C:\Projects\ProjectLocation\Portable\ProjectName\'. 1> Fody: AssemblyPath:

What do I have to do to get Fody working in a .NETStandard project?
