Доброго времени суток) У меня проблема с сервисом WCF. При обращении клиента к сервису, генерируется исключение "Инициализатор типа "System.ServiceModel.ClientBase`1" выдал исключение" в чём может быть причина ошибки и какие есть методы её устранения? Или хотя бы посоветуйте литературу по этой проблеме.
В целом программа работает следующим образом: клиент обращается к удалённому сервису, а сервис обращается к удалённой базе на MSSQL.
