Visual Studio 2022 is the recommended version to build and test the adapter.

To run and debug tests on .NET Framework, load DisableAppDomain.runsettings.

From Visual Studio 2019 version 16.2 preview 4 it is possible to run tests against a selected target framework in the test project, so one can use this to run .NET Core tests. An alternative approach is to make use of the command line. If you need to frequently debug into .NET Core tests, you can temporarily switch the order of the <TargetFrameworks> in NUnit.TestAdapter.Tests.csproj.

The mock-assembly tests are not for direct running.

See for more details.

Debugger source-stepping

The NuGet package and the VSIX contain source-linked PDBs for the adapter. If you’re in the middle of a debugging session and realize you’d like to be able to step into NUnit adapter code, set breakpoints and watch variables, follow these steps.
