Debug.WriteLine没有在Visual Studio 2010中将输出写入OutputWindows

Question

Tools|Options|Debugging Redirect all Output to Immediate is unchecked.
Tools|Options|Debugging|Output Window General output settings are all ON. Debug configuration is activated, define DEBUG constant is checked.

Still Debug.WriteLine("test") writes nothing to Output Window(Cant capture it in DebugView from sysinternals too). What can cause that?

Answer 1

Had this in config file, hope that can help someone else:

<system.diagnostics>
    <trace>
      <listeners>
          <clear/>
      </listeners>
    </trace>
  </system.diagnostics>

removed clear, now everything works. Thank you @Hans Passant.

Answer 2

or use this:

System.Diagnostics.Debug.Listeners(0).WriteLine

instead of just Debug.WriteLine

Answer 3

I fixed that problem closing the project, delete 'bin' and 'obj' folders. Reopen project and Debug.WriteLine works...

Answer 4

Just want to say for anyone coming to this question that the answer given and which received 0, System.Diagnostics.Debug.Listeners(0).WriteLine worked for me in VS2013. Change console.writeLine and or debug.WriteLine to the above , open your immediate window and output is there. Good luck
