[c#] .net Core 2.0 - Package was restored using .NetFramework 4.6.1 instead of target framework .netCore 2.0. The package may not be fully compatible

I have a .net core 2.0 console app. I'm trying to read files from TFS using the following:

How to get a file from TFS directly into memory (i.e., don't want to read from file system into memory)?

I head over to nuget and install Microsoft.TeamFoundationServer.ExtendedClient and run into this:

Package 'Microsoft.AspNet.WebApi.Client 5.2.2' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.0'. This package may not be fully compatible with your project.

Even after suppressing the warning, I still get the error and can't reference the library. How can I get this reference resolving?

Very easy to repro:

1. New .net core 2.0 console app
2. Copy the method from the above question
3. Try to install the nuget package

For me, I had ~6 different Nuget packages to update and when I selected Microsoft.AspNetCore.All first, I got the referenced error.

I started at the bottom and updated others first (EF Core, EF Design Tools, etc), then when the only one that was left was Microsoft.AspNetCore.All it worked fine.

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.
