Same question I had here, does this need to be public?

If it's something a customer won't understand/use, it could be $(_AndroidEnableDiagnosticCrashReporting) and undocumented. It would only exist as an optional escape hatch.


A boolean property that controls whether the .NET runtime registers
its crash reporting signal handlers before Android's signal chaining
takes place.

When `True`, the .NET runtime's crash reporting logic runs first
when a signal such as `SIGSEGV` or `SIGABRT` is received, allowing
managed callstacks to be logged and a crash report JSON file to be
written to disk before Android's signal handlers terminate the process.

This property is `True` by default.

Added in .NET 11.
