A coworker just ran across this awesome feature in a book so I thought I’d share it.
How many times have you recompiled an app just to get some debug/trace information spit out? In VS 2005 you can have a breakpoint write information to the output window as if you compiled in Debug.WriteLine statements. Just set a Breakpoint, right click on it and select When Hit. In the dialog you can configure what gets printed out.
