title: How can I reference an appSetting in a different part of web.config
body: <p>I have my <code>appSettings</code> defined in a separate config file called <code>Appsettings.Dev.Config</code>, and I include that file inside my <code>web.config</code> file like so</p>
  
  <pre><code>&lt;appSettings configSource="ConfigFiles\AppSettings.Dev.config"/&gt;
  </code></pre>
  
  <p>Lets say one of the settings in the file is</p>
  
  <pre><code>&lt;add key="MailerEmailAccount" value="myemail@myserver.com" /&gt;
  </code></pre>
  
  <p>Can I access the value of the setting <code>MailerEmailAccount</code> elsewhere inside web.config? How?</p>
