WCF 客户端在反序列化操作“userAuthentication”的回复消息正文时出错

问：

我快疯了！收到此错误后，我隔离了代码并回到了基础。我创建了一个 .Net Framework 4.7.1 库，其中包含一个用于外部 SOAP 服务（在 php 中创建）的客户端，负责通过服务引用与 SOAP 服务建立通信并向其发出一些请求。

我创建了一个基本的 WinForms 应用程序，它唯一要做的就是向外部服务调用 userAuthentication 方法，该方法返回一个复杂的“Key”对象。当我从此应用程序调用它时，服务会正确返回响应，并且客户端能够反序列化响应。

当我在应用程序中发出完全相同的请求时，我只能通过扩展性库进行完全访问，服务将返回响应，但客户端无法正确反序列化响应。

在与外部服务通信的 DLL 中，我已经添加了一个 IEndpointBehavior 来获取服务返回的响应，并且无论源应用程序如何，我都可以获得相同的响应。我尝试在响应到达 soap 客户端的反序列化部分之前重新创建响应。

据我了解，我已经分析过，运行时使用的 DLL 在两个应用程序中是相同的......我不知道还能尝试什么，我正在考虑创建一个SOAP服务来与另一个SOAP服务:)

下面是一些代码

初始化和 userAuthentication 调用方法：

EndpointAddress endpoint = new EndpointAddress("https://url/webservice/ws-srv.php");

BasicHttpBinding binding = new BasicHttpBinding();
binding.ReceiveTimeout = new TimeSpan(0, 20, 0);
binding.MaxBufferSize = int.MaxValue;
binding.MaxBufferPoolSize = int.MaxValue;
binding.MaxReceivedMessageSize = int.MaxValue;
binding.MessageEncoding = WSMessageEncoding.Text;

// HTTPS
if (endpoint.Uri.Scheme == Uri.UriSchemeHttps)
{
    binding.Security.Mode = BasicHttpSecurityMode.Transport;
    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
}

// Picks up configuration from the config file.
ChannelFactory<iPortalDocWSPortType> factory
  = new ChannelFactory<iPortalDocWSPortType>(binding, endpoint);

// Add the client side behavior programmatically to all created channels.
factory.Endpoint.Behaviors.Add(new MessageDiagnosticsEndpointBehavior());


// Inicialize services
//_iPortalDocServices = new iPortalDocWS.iPortalDocWSPortTypeClient(binding, endpoint);
_iPortalDocServices = factory.CreateChannel();


_iPortalDocServicesValidation = _iPortalDocServices.userAuthentication("user", "password");
