c# asp.net debug.writeline writes where?

New to c# and .net, working in visual studio 2012. I want to have the ability to display values to an output window for debug purposes. I am very familiar with the watch windows, but that does not meet my current needs.

My most recent effort I took the exact sample from the msdn website. 

   Debug.Listeners.Add(new TextWriterTraceListener(Console.Out));
   Debug.AutoFlush = true;
   Debug.Indent();
   Debug.WriteLine("Entering Main");
   Console.WriteLine("Hello World.");
   Debug.WriteLine("Exiting Main"); 
   Debug.Unindent();

This example can be found at http://msdn.microsoft.com/en-us/library/system.diagnostics.debug%28v=vs.71%29.aspx

I added a breakpoint on the very next line after the above code. When I hit the breakpoint I have no errors displaying and my output window has none of the anticipated content. I do have the using System.Diagnostics set.

As described in MSDN, System.Diagnostics.Debug writes their messages into all subscribed TraceListeners (http://msdn.microsoft.com/en-us/library/system.diagnostics.tracelistener.aspx). Note that you should #define TRACE or add /d:TRACE when you compile your program. You can setup your listeners in configuration file like this.

<configuration>
  <system.diagnostics>
    <trace autoflush="false" indentsize="4">
      <listeners>
        <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="TextWriterOutput.log" />
        <remove name="Default" />
      </listeners>
    </trace>
  </system.diagnostics>
</configuration>
