title: How to keep private data separate in an open source ASP.NET MVC application
body: <p>In an open source ASP.NET application I'm working on, I need to keep certain data in the configuration file private, while still keeping it easy for people to build and debug it on their own machine. This is data such as API keys, Mail Settings, etc..</p>
  
  <p>How would I keep this data separate and out of the git repository while still allowing people to just pull and build without having to set up a bunch of stuff?</p>
