раздел конфигурации «услуги» не может быть прочитан, поскольку в нем отсутствует объявление раздела

Я создал службу WCF в Visual Studio 2012. Когда я начал ее отлаживать, тестовый клиент WCF показал ошибку:

«раздел конфигурации« услуги »не может быть прочитан, поскольку в нем отсутствует объявление раздела»

Это не проблема IIS, поскольку я использую тестовый клиент WCF, когда пытаюсь отлаживать службу.

Это весь файл web.config:
