        public ActionResult Details(int id)
        {
            var Product = storeDB.Products.Find(id);

            return View(Product);
        }
        //
        // GET: /Store/Browse?Category=Games

    }
} 

Can you please give me the correct form of connection string to an SQL server

Answer 1

Press f12 on OnlineStoreEntities class then check the connectionString mentioned in OnlineStoreEntities :base("connectionstringName") . Check the connection string name in webconfig. In web config you can change the connection string values.
