Monotouch 4.0.6: ошибка сериализации с использованием служб WCF

Question

Я использую Mono 2.10, и я только что обновился до Monotouch 4.0 .

В моем приложении произошла ошибка:

System.NullReferenceException: Object reference not set to an instance of an object
  at System.ServiceModel.Dispatcher.BaseMessagesFormatter.DeserializeReply (System.ServiceModel.Channels.Message message, System.Object[] parameters) [0x000e3] in /Developer/MonoTouch/Source/mono/mcs/class/System.ServiceModel/System.ServiceModel.Dispatcher/BaseMessagesFormatter.cs:281

Что происходит?Спасибо.

PS В предыдущей версии MT (3.2.6) код работал отлично.

ОБНОВЛЕНИЕ 1:

I 'мы перекомпилировали приложение.Теперь исключение следующее:

ОБНОВЛЕНИЕ 2:

Я использую моно версию 2.10.5 и MT 4.0.6.Я использую WCF и пытаюсь вызвать внешний веб-сервис.

Я использую следующий фрагмент кода для вызова WS:

CustomBinding custom = new CustomBinding(new BinaryMessageEncodingBindingElement(),
    new HttpTransportBindingElement()
    {
       MaxReceivedMessageSize = 2147483647,
       MaxBufferSize = 2147483647
    }
);                  

EndpointAddress endpoint = new EndpointAddress(myUrl);
client = new MyServiceClient(custom, endpoint);

Это исключение перехвачено:

System.Net.WebException: There was an error on processing web request: Status code 400(BadRequest): Bad Request
  at System.ServiceModel.Channels.HttpRequestChannel+HttpChannelRequestAsyncResult.WaitEnd () [0x0003b] in /Developer/MonoTouch/Source/mono/mcs/class/System.ServiceModel/System.ServiceModel.Channels/HttpRequestChannel.cs:435

Если я использую basicHttpBinding, ничего не происходит.Похоже, сообщение потеряно в сети.

client = new MyServiceClient(new BasicHttpBinding(BasicHttpSecurityMode.None), new EndpointAddress(myUrl + "/basic"));

Структура, возвращаемая из WS, содержит список элементов MyClass.Класс MyClass был помечен атрибутом [DataContract], а члены - атрибутом [DataMember].Если служба возвращает только строки, int или enums, результат в порядке.

ПРИМЕЧАНИЕ. При использовании моно версии 2.10 и MT 3.2.6 WS работает в обеих ситуациях.

Есть предложения?Заранее спасибо.
