NU1701: Package 'Unity3D.SDK 2020.1.15.1' was restored using NETFramework...

Unity Engine

I get the following warning when trying to install the Unity3D.SDK package:

Seems odd; shouldn’t it be targeting netstandard now?

(This is, obviously, trying to build a package externally without using the unity editor, which can be imported later, but can benefit from the vastly better dotnet tooling that exists now)

Repro:

dotnet new classlib --name TestUnity
dotnet add TestUnity package Unity3D.SDK

The Unity3D.SDK package on nuget, as far as I know is not produced by unity, and it’s just puts the assemblies from the installed unity editor to nuget. Those DLL-s are still targeting .net framewok.
