title: How to create a clustered index when using code-first migration with Entity Framework and SQL Server
body: <p>I have a <code>MessageModel</code> with a timestamp attribute of when the message was created. I would like to make a clustered index on this long attribute. I hope to achieve a query speed-up when doing a query to get all messages newer than a certain timestamp. The timestamp value is never changed after creation. I currently have a regular index on a int <code>Id</code> attribute. </p>
  
  <p>How can I add a clustered index on a models attribute using Entity Framework code-first migration in ASP.NET MVC 4.5?</p>
