Why is log4net not writing to a file?

I have added all parts of log4net, however it doesn't write to the file.
I'm working with the VS2012 LoadTest project.

Neither the System.Console.WriteLine or Debug.WriteLine() work, when running the LoadTest project.

I've added the assembly info line:

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "web.config", Watch = true)]   //For log4net 1.2.10.0

I've:
- added webconfig section
- initialized an configured an XML initializer
- initialized new log4net with the proper log

My app.config: 

  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

  <log4net debug="true">
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Settings_CacheExplosion.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
      </layout>
    </appender>

    <root>
      <level value="DEBUG" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>

</configuration>

My class:

use <param name = "Activity" value="Settings_CacheExplosion.txt" /> instead of <file value="Settings_CacheExplosion.txt" />. in your xml configuration section.

Looking at your app.config:

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

This works to ensure that the app will refuse to start on .NET 4.0 with an error on startup.

If you are using Framework .NET4.5, log4net does not support it. See frameworks section in http://logging.apache.org/log4net/release/features.html

If you want log4net to read from the app.config, you have to add this to your AssemblyInfo.cs file:

[assembly: log4net.Config.XmlConfigurator(Watch = true)]
