В базе данных ASP.NET сущность fremwork в MVC, во-первых , контроллер [GETPOST] ActionRresult и [протоколы HttpPost] ActionResult ,
[HTTPPOST] ActionResult не запускается и хотя ошибка

когда я запускаю проект ,проект также запускается, но когда я сохраняю данные в текстовом поле и
нажмите на кнопку Создать ошибка отображается на экране

Ошибка сервера в приложении'/'. Ресурс не может быть найден. Описание: HTTP 404. Искомый ресурс (или одна из его зависимостей) может быть удален, изменено его имя или временно недоступен. Пожалуйста, просмотрите следующий URL-адрес и убедитесь, что он написан правильно. Запрошенный URL-адрес: / ,

где я должен дать url-адрес ?
