... only ever seen there.

Saw at least one instance of this crash during a test run:

I was not able to reproduce the issue after the fix, however the MacOS build is still very unstable on the build servers.

Build on one CPU only

Maybe this avoids the concurrency problems?

Make sure there's only one .csproj per directory

Therefore split up sample folders containing multiple
projects into subfolders. This fixes the macOS build and
also some weird issues on other operating systems (such
as the debugger getting confused about which one to execute)
@pgrawehr
Also update the solution files

Make sure all the sample projects sit in their own folder - this fixes the MacOS build and also some potential other problems.
