The model backing the ‘contextname’ context has changed since the database was created. Consider using code First Migration to update the database (http://go.microsoft.com/fwlink/?LinkId=238269

Solution 1: Create a static function in the Context class

public static void InitializeDataContext()

        {

            Database.SetInitializer<YourContextClass>(null);

        }

Call InitializeDataContext() method from Application_Start() method of global.asax

protected void Application_Start()

        {

            AreaRegistration.RegisterAllAreas();

            RegisterGlobalFilters(GlobalFilters.Filters);

            RegisterRoutes(RouteTable.Routes);

            SmokeTest.InitializeDataContext();

        }
