v4.4.0 causes missing method exception for System.Text.Json

[gregsdennis]

Originally reported here.

Minimally reproducible example:
TestProject1.zip

Error occurs when the test project runs in a .Net version prior to 7.0 and references a .Net Standard 2 project that contains a reference to System.Text.Json Nuget package v7.

Example solution contains:

• ClassLibrary1 - netstandard2.0
  • references System.Text.Json Nuget package v7
• TestProject1 - netcoreapp3.1;net6.0;net7.0
  • references NUnit3TestAdapter v4.3.1
  • references ClassLibrary1
  • passes all tests
• TestProject2 - netcoreapp3.1;net6.0;net7.0
  • references NUnit3TestAdapter v4.4.0
  • references ClassLibrary1
  • passes net7.0, fails netcoreapp3.1 & net6.0

Note that this also occurs referencing System.Text.Json Nuget package v6.*.

can u try 4.4.2

[gregsdennis]

Yeah, 4.4.2 seems to work.

It's a really weird bug though. If you have an explanation as to what's going on, I'd love to read about it.

I'd also recommend unlisting 4.4.0.

@gregsdennis nunit/nunit3-vs-adapter#1066

and i already suggested unlisting nunit/nunit3-vs-adapter#1066 (comment) but not my call

@gregsdennis More details here https://docs.nunit.org/articles/vs-test-adapter/AdapterV4-Release-Notes.html and in the four issues whereas the one @SimonCropp mentioned is one of those.
The underlying cause is in the NUnit.Engine 3.16.3 (and ...2) , see #1324 . The fix in the adapter was to use a private build of 3.15.2 enhanced with the .net 8 code, so a pre-release of a 3.15.3 version.

And, v 4.4.0 is now unlisted.

[OsirisTerje]

Since this issue contains a repro project (thanks @gregsdennis ), I'll move it to the console/engine repo so that it can be used with the #1324 issue there.
