Hang dumps aren't even created on macOS agents, by the look of it. Errors about the platform not supporting it. I wonder what GitHub Actions could possibly do differently since this appears to be a limitation in the dotnet test
tooling.
Dmp files are created on linux and Windows, but I don't see them included in any published artifact. I know I had at least that working in the past. I'll have to investigate what happened and get that fixed.
I can verify that dmp files are created on the GitHub Action macOS agent when the testhost is forcibly closed due to a timeout. I had a deadlock in my code. Interestingly, if you look at build log, Blame says the platform is not supported yet a hangdump is being created.
Starting test execution, please wait...

Thanks for that. Interestingly, once I fixed the dmp collection problem that applied to all agents, and extended the mock test hang from 60s to 120s, I got dumps for all three OSs in Azure Pipelines. GitHub worked all along I think because it doesn't set an AzP env var that was taking my script down a particular path that no longer applies. I'll push the fix shortly.
Hang dumps are not being uploaded on MacOS Azure pipeline agents. GitHub Actions work fine. When I open a TRX, the following dialog shows the relative path for a macOS hang dump (ignore the downloads folder prefix).
