title: Storing database settings outside app.config
body: <p>I've been writing a c# exe that will be running on a live web server, but I want to be able to test it on our staging server. Since the staging server has different database settings (in the app.config) from my localhost, is there any way I can store the connection string outside the app.config so that I can easily get to it?</p>
  
  <p>Also, is it possible to store the database connection string, then access it via the app.config? This might sound odd, but I'm using a dll from a CMS that uses the value in the .config file.</p>
