title: Add index in EF Model First design
body: <p>I like the option of doing model first design with the Entity Framework (4). However, I haven't been able to find out how to add an additional index to a table besides the primary key. </p>
  
  <p>Is this possible in the visual designer? Or do you need to add an index manually after creating the database (which would be a shortcoming of the designer)?</p>
