It works fine for me, with no setup. Since it's just a .NET Framework API call, I can't imagine why it wouldn't be working...
(Nice - I had not used DbgView.exe before, cool tool! [link:live.sysinternals.com] )
Thanks for the impressively quick reply. Good to hear that it works on your computer with no additional setup. I will have a try on a different computer and see if I have somehow messed the installation up on this one [:)].
Hello again
Somehow I must have managed to either remove or not have either of the TRACE constant or the DEBUG constant defined in the first place, and not just on my home computer either.
Well at least I'm consistent in my setups [;)].
For anyone else that might have fallen into this trap - it's easy to mend if this is all that is wrong:
- When building debug from Visual Studio: If you are using the debug build and want to use the trace and/or debug functions, go to the project's properties, the build tab and make sure "Define DEBUG constant" and "Define TRACE constant" are checked.
- When running FSI do not just start it by typing "fsi.exe"; instead type e.g. "fsi.exe --define:DEBUG". This allows you to actually get a response in DebugView when next issuing System.Diagnostics.Debug.WriteLine "Now it works!";; .
- The FSI running as a tool in a window inside Visual Studio can be configured from the menu item "F# Tools" -> "F# Interactive" -> Misc. At the "F# Interactive options" line I had "--optimize"; now I have "--optimize -d:DEBUG".
Best regards
Robert

From a C# project I can use
System.Diagnostics.Debug.WriteLine "Some message for listeners."
System.Diagnostics.Trace.WriteLine "Some other message for listeners."
and I will see the messages in DebugView from Sysinternals but when I try in a F# project or type it in F# Interactive I do not get an output.Is there something I need to set up to have the same functionality from my F# projects?
