VS runner does not resolve on netstandard2.0 targets.

It seems all the other nuget packages except for the VS one to integrate with Visual Studio one resolves for netstandard2.0 though,

While all but the regular Xunit package resolves for net40 target in sdk style projects, both frameworks I got to test on as well.

Writing tests in netstandard is not supported. https://xunit.net/docs/why-no-netstandard

The minimum supported version of .NET Framework is 4.5.2 (for xUnit.net v2).

If your tests must be written in .NET 4.0 then you can use xUnit.net 1.x, but it is several years old and no long developed or supported.
