Пожалуйста, помогите мне !!!
Я пытаюсь создать приложение, использующее контракты обратных вызовов. Мое приложение отлично работает как на клиенте, так и на сервере на одном компьютере, но когда я пытаюсь получить доступ к сервису с другого компьютера, я получаю тайм-аут исключения (операция din не завершено в течение выделенного времени ожидания). Клиент считывает некоторые значения, выбрасывая службу из базы данных, которая находится на сервере. Я не знаю, где моя ошибка. Я попытался поместить клиента в виртуальную машину и службу (и база данных) на реальной машине.
Вот мой файл конфигурации сервера:
