title: App.config - custom section not working
body: <p>I recently started building a console version of a web application. I copied my custom sections from my web.config. to my app.config. When I go to get config information i get this error:</p>
  
  <p>An error occurred creating the configuration section handler for x/y: Could not load type 'x' from assembly 'System.Configuration</p>
  
  <p>The line that it is not liking is:</p>
  
  <p>return ConfigurationManager.GetSection("X/Y") as Z;</p>
  
  <p>Anyone run into something like this?</p>
  
  <p>I was able to add </p>
  
  <pre><code>&lt;add key="IsReadable" value="0"/&gt; 
  </code></pre>
  
  <p>in the appSettings and read it.</p>
  
  <p>Addition:</p>
  
  <p>I do actually have this defined about the custom section:</p>
  
  <pre><code>  &lt;configSections&gt;
      &lt;sectionGroup name="x"&gt;
        &lt;section name="y" type="zzzzz"/&gt;
      &lt;/sectionGroup&gt;
  
    &lt;/configSections&gt;
  </code></pre>
