Use metadata buddy classes

Ex:

[MetadataType(typeof(MyClassMetadata)]
public partial class MyClass
{
    public class MyClassMetadata
    {
         [StringLength(30)]
         public string FirstName {get;set;}

         [StringLength(30)]
         [Required]
         public string LastName {get;set;}    
    }
}
