@JoeRobich Can you take a look at these failing tests to see if they're related to your changes?

[JoeRobich]

@brettfo They are unrelated.
Roslyn CI Linux_Test mono failure previously logged as #30386
windows_release_vs-integration_prtest failure (IPC Port) previously logged as #29001

@JoeRobich Thanks for pointing that out. Can you find a lead to approve and complete the merge, then? I don't have permissions to force it through.
