I had this working and now it has stopped. I have checked the box Tools | Options | Debugging | General | Redirect all Output Window text to Immediate Window, but it is not working. The Immediate Window remains blank.
I did have this working. I have to be honest, though, maybe it was working when I ran a Windows Phone project in the simulator on the PC; I am now running an iOS project in the simulator on the Mac. Could someone give it a go and let me know if it works for either Windows Phone or iOS projects?
