Thanks for sharing this issue.

This is caused by an inconsistency between the xunit runner libraries that are packaged with NCrunch, and the xunit runtime libraries referenced from your test project.

Basically, the main xunit Nuget package doesn't ship with the runner libraries, so it's the responsibility of runners (like NCrunch) to provide them. The current set of binaries packaged with NCrunch is consistent with xunit 0.3.0-pre.18, which seems to have a clash with 0.4.0-pre.20. The reason for this is because we finalised our integration with xunit about 2-3 weeks ago, at which point 0.3.0-pre.18 was the latest version. The smart move would have been for us to update our binaries just prior to our own release ... but of course, we forgot to do that. So when NCrunch v5.10 went out yesterday it was already out of alignment with the latest pre-release of xunit.

Because it's expected that xunit is likely to still see changes like this while in a PR state, we did try to implement forwards compatibility with future versions of the libraries, but depending on the versions involved, you may still need to have the runner library versions match those of the runtime ones. NCrunch has a built-in override through which it will always use the runner libraries being referenced by your project before using the ones packaged with itself. To use this override, you'll need to have your own copies of these runner libraries:

xunit.v3.common.dll
xunit.v3.runner.common.dll
xunit.v3.runner.utility.netcore.dll or xunit.v3.runner.utility.netfx.dll (depending on your platform)
xunit.v3.runner.inproc.console.dll

They need to be referenced directly from the project to work. I don't think there is a Nuget reference available for these yet, so it would probably need to be done using a <Reference Include="AssemblyName.dll" /> inside the project file (i.e. old school assembly reference). I've just checked quickly and it looks like it might take a few steps to get hold of these files. You might need to build them from source.

Alternatively, you can use a slightly older version of xunit, v0.3.0-pre.18, which should work just fine.

We'll update our own copies of the binaries the next time we push a build.

Thanks.for the detailed response.

I'll downgrade to 0.3.0-pre.18 for now and will upgrade on next ncrunch build.

Cheers!
