Error: "Specified method is not supported" in VS 2017

[CodeStoneK]

I have an Asp.Net Core project referencing my own lib, which is dependent on another library. I have all 3 projects opened in one solution, referencing the dependencies via NuGet. When I try to switch from NuGet to Project reference, I get the following error:

"Specified method is not supported."

Please let me know what I am missing.

Thanks.

NuGetReferenceSwitcher does not work with the new csproj format (i.e. PackageReference tags). It only works with the old full .NET Framework projects... I'm working on new tools to support .net standard and .net core
