NuGet package adds .NET Standard references even when adding the dependency as a full-framework reference

Hello,

Remotion.Linq nuget package, version 2.1.1, pulls a bunch of .NET System nugets, even though that the target framework is not ".NET Standard" but .NET Framework 4.6.

These unnecessary references are collided with Postsharp reference resolver (the project would not compile, error message is attached at the bottom).

Can you please whether add a .NET Framework target in your nuget package, or simply remove the .NET Standard one (as it used to be until the latest release).

Thanks,
Miri
