Я получаю это исключение в клиентском приложении, не знаю, как пройти через это.
Я сталкиваюсь с этим исключением, когда возвращаемые данные (список цен) превышают 15 МБ, но работают с размером сообщения менее 15 МБ.
Сообщение об ошибке:
Произошла ошибка при получении ответа HTTP на "http://localhost:8782/CMDService".. Это может быть связано с тем, что привязка конечной точки службы не использует протокол HTTP. Это также может быть связано с тем, что сервер прерывает контекст запроса HTTP возможно, из-за закрытия службы.) Подробнее см. в журналах сервера.
