Question

I’m using mvc 4, with database first.

Everytime I refresh the model.edmx file, the display name attribute I added is removed. How can I the keep display name attribute between refreshes?

You are going to want to use System.ComponentModel.DataAnnotations. Here is a simplistic Example for a ‘User’ table in EF to show you how:

namespace YourNamespace.BlaBlaBla
{
    [MetadataType(typeof(UserHelper))]
    public partial class User { }

    public class UserHelper
    {
        [Display(Name = "Your New Title For Name")]
        public string Name { get; set; }
    }
}

You can also include validation in your class as well. Be sure it is a partial class named the exact same – also do not forget that it must be in the exact same namespace as your .edmx.
