How to write just message to debug output with Enterprise Library Logging?

Question

I want to implement logging with EntLib Logging and hook up two TraceListeners for category \"Debugging\". One will write those messages to file and other will output them to sy

I found a nice walkthrough on MSDN: Creating a Custom Trace Listener

It does exactly what I need. Here is a full code I ended up with:

using System;
using System.Diagnostics;
using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Logging;
using Microsoft.Practices.EnterpriseLibrary.Logging.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners;

namespace Common.Utils
{
    [ConfigurationElementType(typeof(CustomTraceListenerData))]
    public class FormattedDebugWriterTraceListener : CustomTraceListener
    {
        public override void TraceData(TraceEventCache eventCache, string source, TraceEventType eventType, int id, object data)
        {
            if (data is LogEntry && this.Formatter != null)
            {
                this.WriteLine(this.Formatter.Format(data as LogEntry));
            }
            else
            {
                this.WriteLine(data.ToString());
            }
        }

        public override void Write(string message)
        {
            Debug.Write(message);
        }

        public override void WriteLine(string message)
        {
            Debug.WriteLine(message);
        }

    }
}

Configuration file:

And the usage goes like this:

Debug.Write("Debug.Write test");
Logger.Write("EntLib test", "Debugging");

Both end up in debug output easily traceable by DbgView.
