An exception of type 'System.Data.Entity.Core.MetadataException' occurred in EntityFramework.dll but was not handled in user code

        [HttpGet]
        public ActionResult AddOrEdit(int id=0)
        {
            tblnewregistration userModel = new tblnewregistration();
            return View(userModel);
        }
        [HttpPost]
        public ActionResult AddOrEdit(tblnewregistration userModel)
        {
            using(DbModels dbModel=new DbModels())
            {
                if (dbModel.tblnewregistrations.Any(x => x.Username == userModel.Username))
                {
                    ViewBag.DuplicateMessage = "Username already exist";
                    return View("AddOrEdit", userModel);
                }
                else
                {
                    dbModel.tblnewregistrations.Add(userModel);
                    dbModel.SaveChanges();
                }
            }
