I wish to add a reference to the EntityFramework.Core NuGet packet (currently at version 7.0.0-rc1-final) to a portable class library, targetting both .NET framework 4.6 and Windows Universal 10.0. However I'm getting the following output:
Restoring packages for 'ClassLibrary1'.

I have no idea what this .Net v5.0 reference means and where it comes from. To make it even more strange, it is perfectly possible to add the EFcore packet to class libraries solely targeted to Universal windows or .Net framework v4.6:
As shown, you can add the packet to individual libraries but not to a portable library. Why is this?
