title: How to have different web.config settings for my local machine?
body: <p>I'm finding myself having to manually update my DefaultConnection connection string in my web.config when I run locally.  How can I automatically detect when I'm running locally and - when I am - overwrite the default connection string?  </p>
  
  <p>I have debug/release transformations working, but these are for deployment.  I'm looking for a way to add another option - "local" - if there's any way to do it (or something like it).  </p>
