Solution 1

To utilize Trace capabilities of the .NET framework, you first have to set up a trace listener - an actual storage to where the trace messages will go...
In you code there is only messages, but nowhere to see one who listens to those messages...
Se the simple, but complete sample at MSDN...
Trace Class (System.Diagnostics)[^]

Solution 2

You need to set up a Trace Listener[^] to determine where you want the output to go. Without that, your output just goes to the default listener, which is the debug window. There are many types of Listener for the Event Log, a Log File, the Console, etc... have a read from the link, and I'm sure you'll be able to take it from there.

"goes to the default listener, which is the debug window" - while debugging...
However tracing is much more for production health monitoring and in that case if no listener it goes nowhere...
