Question

I tried to configure log4net for logging everything to the console output. I have a config file named Log4Net.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="INFO" />
      <appender-ref ref="ConsoleAppender" />
    </root>
  </log4net>
</configuration>

and I have my main class (just a testing case)

namespace TestLog4Net {
    class Program {
        private static readonly ILog log = LogManager.GetLogger(typeof(Program));

        static void Main(string[] args) {
            log.Info("Info");
            log.Error("Error");
            Console.ReadKey();
        }
    }
}

I added these lines to the AssemblyInfo.cs

[assembly: log4net.Config.XmlConfigurator(
ConfigFile = "Log4Net.config", Watch = true)]

But now nothing is logged, can someone explain this?

When you have log4net config in a separate config file you should not include the configuration and configSections elements. log4net should be the top level element after the xml declartion.
