Referencing mscorlib 4.0.0.0 from .NET Core 1.0 class library

Question

I have a .NET Core 1.0 class library which targets .NET 4.6.1 and references the .NET Standard Library 1.6.0 and Identity Framework 2.2.1

project.json

{
    "version": "1.0.0-*",

    "dependencies": {
        "Microsoft.AspNet.Identity.EntityFramework": "2.2.1",
        "System.Runtime": "4.1.0",
        "NETStandard.Library": "1.6.0"
    },

    "frameworks": {
        "netstandard1.6": {
            "imports": [
                "net461"
            ]
        }
    }
}

In my project I'm just creating the identity models, which extend the base Identity Framework models (User, Role etc). When I try to compile, this happens...

Any ideas how to resolve this?

Answer 1

Microsoft has a nuget package that can help. I don't know the specifics of how it works but it resolved my dependency issues:

https://www.nuget.org/packages/Microsoft.NETCore.Portable.Compatibility/

Or simply run this in the package manager console:

Install-Package Microsoft.NETCore.Portable.Compatibility -Version 1.0.1

edit: This was added to a .net core 1.1 project.
