Попытка заставить MTOM работать в клиенте WCF. Конкретная функция, которую я пытаюсь использовать, отправляет массив байтов в формате MTOM документа PDF. Использование SoapUI для тестирования API с помощью WSDL работает нормально; однако, когда я пытаюсь сделать то же самое в клиенте, я получаю следующую ошибку:
Error creating a reader for the MTOM message

Теперь я искал повсюду и не могу найти ничего, что имело бы отношение к этой ошибке, кроме возможно этого: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/73039d75-e078-436b-a8ab-d8c7197a976b
Рекомендация в этой ссылке, однако, не имеет смысла для меня. Я не вижу нигде в своем коде, где ответное сообщение существует как объект, где я мог бы его изменить. И вот я здесь. Клиент, который у меня есть, предельно прост: он состоит из прокси-класса, сгенерированного svcutil, прим. 10 строк кода для вызова и файл app.config. Я добавил информацию о сертификате в файл конфигурации и изменил messageEncoding на Mtom, но помимо этого все это сгенерировано svcutil.
Вот как выглядит клиентский код (как видите, очень просто):
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.ServiceModel;
using System.Text;
namespace Client
{
class Program
{
static void Main(string[] args)
{
try
{
WsApiServicePortTypeClient client = new WsApiServicePortTypeClient();
byte[] doc = client.getRecordDoc("username0000", "1234567");
File.WriteAllBytes(@"C:\TestRecords\wcf-test.pdf", doc);
Console.WriteLine("Ok, check it now.");
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine("ERROR: " + ex.Message + Environment.NewLine
+ ex.GetBaseException().ToString() + Environment.NewLine
+ ex.StackTrace + Environment.NewLine);
Console.ReadLine();
}
}
}
}
Из прокси-класса:

Я думаю, что это как-то связано с оболочкой контракта, на что указывают сообщения CODEGEN в файле прокси-класса. Однако я не могу найти ничего об этом сообщении, что подтверждало бы это.
Любая помощь приветствуется.
