title: ASP.NET MVC: Use different databases for debug / release
body: <p>How can I easily use two different databases for debug and release scenarios?<br>
  I don't want to need to remember to change the data source connection strings every time I publish a new version of my application but I also don't want to test new code on the working database ...</p>
  
  <p>Is there something like a debug / release switch?</p>
