У меня возникла особая проблема, связанная с размещенной службой WCF (.NET Framework 4, IIS 7, Windows Standard Standard SP2).
После того, как я развернул службу, он работает отлично в течение некоторого времени, и он сам умирает, бросая исключение, не найденное в файле. Детали исключения приведены ниже.
Приложение размещено в IIS7 с определенным пулом приложений, указывающим на версию .NET Framework 4. Я использовал FusionLog, чтобы найти больше на отсутствующей сборке, не повезло. Однако, если я удалю все сборки с размещенного сервера и скопирую его снова из папки сборки, он снова начнет работать без проблем. Я не могу объяснить это поведение и много раз искал/пытался найти ответ. Чтобы предоставить дополнительную информацию, служба является локальной сборкой, и я использую Enterprise Library для обработки исключений и ведения журнала. Служба WCF нас использует httpBinding. Сборка построена на основе отладки. Пожалуйста, помогите.
