I have this on my Module

Module
Code:
    public class Person
    {
        public int ID { get; set; }
        [Required]
        [StringLength(30)]
        public string First { get; set; }
        [Required]
        [StringLength(30)]
        public string Last { get; set; }
        public DateTime BirthDate { get; set; }
    }

    public class PersonContext : DbContext
    {
        public DbSet<Person> People { get; set; }
    }
and this on Controller

Controller
Code:
        // GET: /Person/Create

        public ActionResult Create(Person person)
        {
            db.People.Add(person);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
Every type I click the Create link, I'm encountering this error:

Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
