c# - Required option with TryUpdateModel still saves into the db, when not inserting anything in the fields for the model

Question

[Required] on properties with an TryUpdateModel doesn't work. I have a model where I'm using [Required] for each property. Then in the Controller I use an TryUpdateModel. What I think that should happen was that the Employee wasn't saved into the db and it would say that the fields are required. But it does. With null values

 public class Employee
    {
        //[Required] betyder at den er p?kr?vet
        public int Id { get; set; }
        [Required]
        public string Name { get; set; }
        [Required]
        public string Gender { get; set; }
        [Required]
        public string City { get; set; }

        //Med sp?rgsm?l efter giver den mulighed for at DateOfBirth kan v?re null
        [Required]
        public DateTime? DateOfBirth { get; set; }
    }

My Controller

[HttpPost]        
        [ActionName("Create")]
        public ActionResult Create_Post()
        {
            Employee employee = new Employee();
            //ved at bruge TryUpdateModel istedet for UpdateModel 
            TryUpdateModel(employee);

            if (ModelState.IsValid)
            {
                EmployeeBusinessLayer employeeBusinessLayer = new EmployeeBusinessLayer();
                employeeBusinessLayer.AddEmployee(employee);

                return RedirectToAction("Index");
            }
            return View();
        }
