title: Nested Configuration Section app.config
body: <p>I don't find any examples of how to access such a nested configuration section in a app.config</p>
  
  <pre><code>  &lt;my.configuration&gt;
      &lt;emailNotification&gt;
        &lt;to value="me@you.com" /&gt;
        &lt;from value="he@you.com" /&gt;
        &lt;subject value="Subject" /&gt;
        &lt;smtpHost value="smtp.you.com" /&gt;
        &lt;triggers&gt;
          &lt;add name="1" varAlias="Var1" lower="-200" upper="-150"/&gt;
        &lt;/triggers&gt;  
      &lt;/emailNotification&gt;
    &lt;/my.configuration&gt;
  </code></pre>
  
  <p>I used ConfigurationElementCollection and ConfigurationElement before. But I don't know how to do the above?</p>
