Why isn't there a trace level in log4Net?

Question

I was just wondering why there isn't a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are being executed in an application. This feature is a part of log4J.

I know I can create a custom level like is talked about here but I don't want to put time and effort in something I feel should be part of the library itself.

Do you know about a log4net extension library that implements this or why this wasn't a part of the port to .net ?

You can add a Verbose (or Trace level) to log4net by using extension methods. This is what I'm using:

public static class ILogExtentions {            public static void Trace(this ILog log, string message, Exception exception)     {         log.Logger.Log(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType,              log4net.Core.Level.Trace, message, exception);     }      public static void Trace(this ILog log, string message)     {         log.Trace(message, null);     }      public static void Verbose(this ILog log, string message, Exception exception)     {         log.Logger.Log(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType,              log4net.Core.Level.Verbose, message, exception);     }      public static void Verbose(this ILog log, string message)     {         log.Verbose(message, null);     }  } 

Usage example:

public class ClientDAO {     private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(ClientDAO));      public void GetClientByCode()     {         log.Trace("your verbose message here");         //....     } }

There is a trace level in the log4net.Core.Level class http://logging.apache.org/log4net/release/sdk/html/F_log4net_Core_Level_Trace.htm
