title: Could not load file or assembly log4net
body: <p>I have added <code>log4net</code> to my project and it is working just fine on my machine, but when I sent the release version of my application to my colleague, he receives this <code>FileNotFoundException</code>:</p>
  
  <blockquote>
    <p>Could not load file or assembly 'log4net, Version=1.2.13.0,
    Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a'</p>
  </blockquote>
  
  <p>But the strange thing is that in my <code>app.config</code> I'm not even using the above version of log4net: </p>
  
  <pre><code>&lt;section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/&gt;
  &lt;sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"&gt;
  &lt;section name="BizWizard.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/&gt;
  &lt;/sectionGroup&gt;
  </code></pre>
