title: Does Monodevelop support configuration files?
body: <p>I added a file app.config to a C# mono project. </p>
  
  <p>Inside the project I used</p>
  
  <pre><code>foreach (string key in ConfigurationManager.AppSettings)
  {
  string value = ConfigurationManager.AppSettings[key];
  Console.WriteLine("Key: {0}, Value: {1}", key, value);
  }
  </code></pre>
  
  <p>The config file looks like this</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;configuration&gt;
  &lt;appSettings&gt;
  &lt;add key="Key1" value="Kevin" /&gt;
  &lt;add key="Key2" value="150" /&gt;
  &lt;add key="Key3" value="Rice" /&gt;
  &lt;/appSettings&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>No keys are detected. How can I read the config values? </p>
