Question

I\'m using MVC3 VS2010 with EF4.1, I have created my DB using SQL Server and I import it to the MVC3 Web Application.

No, the files will be regenerated every time.

All the classes are defined as partial so you can easily add DataAnnotations using the MetadataTypeAttribute.

Let's say you have a User class defined as follow:

public partial class User {
    public string Name {get;set;}
}

Create a IUser interface

public interface IUser {
   [Required]
   [DisplayName("User name")]
   string Name {get;set;}
}

And then extend the User class to specify that IUser will be used as metadata.

[MetadataType(typeof(IUser))]
public partial class User {} //Empty class body
