Question

Here is my code:

 public ActionResult DeleteItem(int id)
        {
            using (var cont = new PhotoGalleryDBEntities4())
            {
                var refToDel = cont.Referanslars.First(x => x.Id == id);
                if (!ModelState.IsValid)
                    return Content("Referans bulunamadı!");
                _db.Attach(refToDel);
                _db.DeleteObject(refToDel);
                _db.SaveChanges();
                return View();
            }
            return View();
        }

I am getting error in _db.Attach() that is:An entity object cannot be referenced by multiple instances of IEntityChangeTracker. Why is this happenning?
