title: Is there any way for an App.config file to reference another full config file? (.NET)
body: <p><strong>Update: this question, including the title, was rephrased, see history for details</strong>  </p>
  
  <p>I know that the following App.config includes a external file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;configuration&gt;
    &lt;appSettings configSource="appSettings.config"/&gt;
    &lt;system.net&gt;
      &lt;connectionManagement&gt;
        &lt;add address="*" maxconnection="50"/&gt;
      &lt;/connectionManagement&gt;
    &lt;/system.net&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>But I don't know how to move the system.net to the second file. Actually I haven't tried it, but I am almost certain that it will not work, and I want to know if there is an way for an App.config to include another App.config file by reference.</p>
