WCF ошибка при получении ответа HTTP

Question

Я получаю эту ошибку: An unhandled exception of type 'System.ServiceModel.CommunicationException'

полный discripton ошибки:

An unhandled exception of type 'System.ServiceModel.CommunicationException' occurred in mscorlib.dll

Additional information: An error occurred while receiving the HTTP response to http://localhost:8733/Design_Time_Addresses/SnUpdateService/Service1/ . This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

Когда в Clien я пытаюсь получить ответ с потоковыми данными

SnUpdateService.Service1Client SnService = new  SnUpdateService.Service1Client(); 
     SnUpdateService.UpdateFiles com = new SnUpdateService.UpdateFiles(); 
     com.Path = "C:\\temp"; 
     com.SearchType = 1; 
     com.Version = "20150101"; 
     SnUpdateService.UpdateFiles comReturn = new SnUpdateService.UpdateFiles(); 
     comReturn = SnService.GetUpdateFiles(com);//here error 

если нет данных о потоке, все работает нормально.

Что я делаю неправильно?

Это мой клиент конфигурации

<?xml version="1.0" encoding="utf-8" ?> 
    <configuration> 
     <startup> 
     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

Answer 1

Я думаю, что вам не хватает для определения связывания конфигурации BasicHttpBinding_IService1 в файле конфигурации клиента.

Кроме того, вы можете установить includeExceptionDetailInFaults = "False" в значение "true", чтобы получить более подробную трассировку стека. Это помогает вам отлаживать.

Answer 2

У меня была такая же проблема некоторое время назад и разрешила ее, включив 32-разрядные приложения в пул приложений, где размещался мой сервис.
