Since I don't think it's possible to extend the Messenger to log when it sends a message and notifies it's subscribers I went ahead and modified the source.
Now I can follow what the Messenger does it the output window. Verry handy
I could contribute back but its rather ad hoq. Are you considering adding support for hoooking up logging (debug output window, nlog, log4net,...) ?
Thanks for the excellent library, Tom
