WCF возвращает ошибку 400 для очень простого приложения ⇐ C#

[Anonymous]

Я создал очень простое приложение WCF, которое ничего не делает, а лишь возвращает введенное вами входное значение.
При локальном размещении этого приложения в IIS я получаю ответ без каких-либо проблем.
Однако, когда Размещая это приложение на своем сервере Windows 2022, на все запросы я получаю ошибку «400 Bad Request». Что бы я ни пытался сделать.

Код: Выделить всё

    [ServiceContract]
public interface IService1
{

[OperationContract]
string GetData(int value);

[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
}

И реализация GetData:

Код: Выделить всё

    [AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}

public CompositeType GetDataUsingDataContract(CompositeType composite)
{
if (composite == null)
{
throw new ArgumentNullException("composite");
}
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
}

Веб-конфигурация выглядит следующим образом:

В включенной мной трассировке есть исключение типа:

«Возникла проблема с XML, полученным из сети», а затем в исключении: «Неожиданный конец файла».
I Я также попробовал использовать инструмент композитора Fiddler, это моя просьба:

Код: Выделить всё

3

С заголовками:

Код: Выделить всё

Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
Host: localhost
SOAPAction: "http://tempuri.org/IService1/GetData"

Это также дает мне исключение 400 без какой-либо дополнительной информации.
Когда я запускаю URL-адрес в браузере: http://localhost/WcfTest/Service1.svc, я могу убедитесь, что SVC загружен правильно.
Есть идеи, в чем может быть причина этой проблемы?
