DeleteObject method is missing in Entity Framework 4.1

Question

This is driving me crazy. I am getting error that

object doesn\'t contain definition for DeleteObject.

Here is my line of code

Answer 1

  [HttpPost]
        public ActionResult Delete(IEnumerable employeeIdsToDelete)
        {
            var lstemployee = _db.StudentEmployees.Where(x => employeeIdsToDelete.Contains(x.Id));
            foreach (var item in lstemployee)
            {
                _db.StudentEmployees.Remove(item);
            }
            _db.SaveChanges();

            return RedirectToAction("Index");
        }
