How to stop linqpad from displaying the output of statements written in Debug.Writeline?

Linqpad seems to put the listener in the debug.listeners collection, and then display the trace results in the result window, along with any of the results of the query itself.

Is there a way to tell linqpad not to do this, but leave only the existing debug.listeners collection?

I have an assembly that I call from linqpad, which writes the trace to a separate application, but it looks like linqpad cleans up the listeners and inserts its own, ideally I would like the existing listeners to leave tactfully, so I get our normal trace from the library .

Thanks for any Tollo suggestions.
