How to use log4net in a DLL project?

Question

I have a project in which I want to use log.net for logging. When I'm testing my project using a console app program, it does not log anything unless I write the log.net section in the app.config of the test project. How do i fix this?

This is my configuration in my app.config file in the DLL:

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <log4net>
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="MyLogFile.log" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newline%exception" />
      </layout>
    </appender>
    <root>
      <level value ="DEBUG"/>
      <appender-ref ref ="RollingFileAppender"/>
    </root>
  </log4net>

From log.net documentation page: https://logging.apache.org/log.net/release/manual/configuration.html ( Configuration Files section)

The only way to configure an application using the System.Configuration APIs is to call the log.net.Config.XmlConfigurator.Configure() method or the log.net.Config.XmlConfigurator.Configure(ILoggerRepository) method.

Make sure you are initializing log.net on your console app.
