Title
Body
I am trying to figure out how to have a composite key using EF code First 4.1 RC. Currently, I am using the [Key] Data Annotation, but I am unable to specify more than one key. how would one specify a composite key? Here is my Example: public class ActivityType { [Key] public int ActivityID { get; set; } [Required(ErrorMessage = "A ActivityName is required")] [StringLength(50, ErrorMessage = "Activity Name must not exceed 50 characters")] public string ActivityName { get; set; } } I need the "ActivityName" to also be a key. Sure, I can code around this, but thats not good database design.
