Log4net system should be configured only once int the "starting" class of your application (first class used in the application) or any other class but before first logging attempt.. If you configure more times, only the last configuration is used. But you can use log4net in way that every class uses its own appender. RR

I want to have separate log4net configurations for the console application, for the Caller dll, and for the Callee dll. Each of the 3 should write to its own rolling log file appender. I call XmlConfigurator.Configure in the constructor of the Caller, the Callee, and in the Main method of the console application. It ends up that the console application starts writing to its own log file, but then ends up writing into the innermost, the Callee's, log file. I can get the console application to write back to its own log file if I call XmlConfigurator.Configure again before I want to write to the console app's log file. Is that necessary or did I configure this incorrectly? I want to be able to have varying levels of log4net capability and verbosity at each of the 3 levels. Here's the guts of the console application: log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(Assembly.GetExecutingAssembly().Location + ".config")); string message = "message from main generated at : " + DateTime.Now.ToLongTimeString(); _log.Error("error" + message); _log.Warn("warn" + message); _log.Info("info" + message); _log.Debug("debug" + message); Caller caller = new Caller(); caller.MethodOne(); // if the following line is commented out, then the output goes into the Callee's log file (which was the last class to call XmlConfigurator.Configure), not into the console application's log file log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(Assembly.GetExecutingAssembly().Location + ".config")); message = "message from main generated at : " + DateTime.Now.ToLongTimeString(); _log.Error("error" + message); _log.Warn("warn" + message); _log.Info("info" + message); _log.Debug("debug" + message); Caller caller2 = new Caller(); caller2.MethodOne();
