Issue running XUnit tests targeting .NET Core 2.2 framework & latest Microsoft.NET.Test.Sdk (16.5.0)

[temelj]

My findings are reported in a test project that I've created at https://github.com/temelj/xunit-mstest-demo

I know that .NET Core 2.2 is EOL, I have verified that the same happens under .NET Core 2.1 also.

Downgrading to Microsft.NET.Test.Sdk 16.2.0 seems to be ok (I haven't tried any versions in-between)
