Using NSubstitute.Analyzers.CSharp in VisualStudio for Mac 2020 Preview crashes Visual Studio

[iduras3]

Like the title mentions the NSubstitute.Analyzers.CSharp crashes Visual Studio.

Visual Studio Version: 17.0 Preview (17.0 build 4729)
NSubstitute.Analyzers.CSharp 1.0.15

Hi @iduras3, NSubstitute.Analyzers were never tested on VS for Mac. I would assume that underlying analyzers engine is the same as in standard VS, but you never know. Unfortunately I dont have access to Mac so I cant check if this is issue with the package or rather problem with beta version of VS. Can you provide us with some logs from the crash? @nsubstitute/core-contributors do you guys maybe have Mac to check this on your own?

The crash happens as soon as I am opening a test file with the NSubstitute.Analyzers in the project.
The log file: crash-log.txt

I was able to reproduce this on VS 2022 for Mac Preview (17.0 build 4172). I'm updating VS to the latest to see if it still occurs. Builds from the command line seem to work fine. Also noticed Analyzers 1.0.13 seems to work ok, but 1.0.14 and 1.0.15 seem to crash.

I haven't been able to find a good exception message . :-\
