Constrains in DataBase.

Hi, 
If using Code First, you can create the index 
in the DbContext: (http://stackoverflow.com/questions/4995642/add-index-with-entity-framework-code-first-ctp5 and 
http://stackoverflow.com/questions/4413084/unique-constraint-in-entity-framework-code-first)

public class Initializer : IDatabaseInitializer<MyDbContext> {
  public void InitializeDatabase(MyDbContext context) {
    ...
    context.Database.ExecuteSqlCommand("CREATE 
INDEX...");
  }
}

In Model First/Database First, unfortunatelly there's no equivalent for the "Indexed"  attribute in DevForce. (Actually EF does not support it)
