Sorry for my very late reply.
I've put a sample project on github https://github.com/olizit/RimWorld_RemoteDebug
Can you add this sample mod into the RimWorld, start the game with debug mode and attach to it.
When game started, add a function breakpoint inside Xamarin "When an exception is throw" to System.Exception. When game is fully loaded open in game bottom menu "Hello World". A breakpoint should be triggered.
Now you can test a standard breakpoint. Do not forget to add breakpoint in whitespace before the code.
Tell me if it's working or not !
