title: What is the new Startup.cs file for in Visual Studio 2013 projects?
body: <p>I have just installed Visual Studio 2013, created an MVC Web Application project and noticed a new file in the project template called Startup.cs.</p>
  
  <p>What is this, how is this different from Global.asax.cs and are there any good best practices on what to use this for?</p>
