DRI RESPONSE: No longer reproducible.

@abgoswam this line is still present

if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows)) // -rp.txt files are not getting generated for Non-Windows Os

you may try it repro it after removing this if condition

[eerhardt]

Let's use this issue to remove all of the test checks that @Anipik linked above. Once the tests on Linux and macOS are producing and consuming rp files (just like on Windows), we can close this issue.

@Anipik can you verify if this is still valid?
