Why is log4Net not generating a log file in my WCF service?

Hi:

I'm currently having difficulty getting log4net working in my WCF service application.
I'm running the service through VS 2010 (iis express)
I don't see any build errors or run time exceptions.
But the desired log file is not getting generated.

The WCF service implementation is broken into 2 parts (service library and service)
TestServiceLibrary.dll
TestService.dll

This is what the log4net configuration look like in my app.config file:
TestServiceLibrary -> App.config


  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false"/>
  </configSections>
  <log4net debug="false">
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="C:\\logs\\TestService_log.txt"/>
      <!-- the file to write to. change for your location and service -->
      <appendToFile value="true"/>
      <immediateFlush value="true" />
      <datePattern value="yyyyMMdd"/>
      <rollingStyle value="Date"/>
      <!-- defines what the log message looks like. you want the timestamp and message, the rest is more or less decoration -->
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline"/>
      </layout>
    </appender>
    <appender name="DebugAppender" type="log4net.Appender.DebugAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline"/>
      </layout>
    </appender>
    <root>
      <level value="DEBUG"/>
      <!-- determines what 'level' of message to output. take as-is -->
      <appender-ref ref="RollingLogFileAppender" />
      <appender-ref ref="DebugAppender"/>
    </root>
  </log4net>

Open in new window



Actual calls to Log4net takes place in TestServiceLibrary.dll:
This my code snippet
private static ILog m_log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
m_log.Debug("Debug Test Log4Net write");
m_log.Debug("Info Test Log4Net write");

Open in new window


When I examine m_log at run time, all the following fields are set to false:
IsDebugEnabled
IsErrorEnabled
IsFatalEnabled
IsInfoEnabled
IsWarningEnabled
