WCF流式响应在将Config移动到代码后进行缓冲

我有一个客户端-服务器应用程序，它使用带有streamedResponse服务的net.tcp绑定，所有WCF配置都已在app.config中定义，一切都很好，没有问题，我不得不从客户端应用程序中删除配置并在代码中定义它们，服务器上没有任何更改，但客户端似乎通过此转换将响应作为缓冲而不是流式传输，以下是我如何在客户端代码中构建服务：

public static BuildChannelFactory()
{
channelFactorty = new ChannelFactory<IMyService>(GetStreamBinding(),
                   Address);

            channelFactorty .Endpoint.Address = new EndpointAddress(
                 new Uri(Address), EndpointIdentity.CreateDnsIdentity(
                 "MyServer"));

            channelFactorty.Credentials.ClientCertificate.SetCertificate(
                StoreLocation.LocalMachine, StoreName.Root,   
                X509FindType.FindBySubjectName,
               "MySubject");
            channelFactorty.Credentials.ServiceCertificate.
Authentication.CertificateValidationMode =  
System.ServiceModel.Security.X509CertificateValidationMode.Custom;
channelFactortyCredentials.ServiceCertificate.Authentication.
CustomCertificateValidator = MyCertificateValidator;    
}

private static NetTcpBinding GetStreamBinding()
    {
          NetTcpBinding streamBinding = new NetTcpBinding
            {
                Name = "streamBinding",
                ReceiveTimeout = new TimeSpan(2, 0, 0),
                SendTimeout = new TimeSpan(0, 2, 0),
                MaxBufferSize = int.MaxValue,
                MaxReceivedMessageSize = int.MaxValue,
                TransferMode = TransferMode.StreamedResponse,
                ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas
                {
                    MaxArrayLength = int.MaxValue,
                    MaxStringContentLength = int.MaxValue
                }
            };
            streamBinding .Security.Mode = SecurityMode.Transport;
            streamBinding .Security.Transport.ClientCredentialType =  
            TcpClientCredentialType.Certificate;
        }
        return streamBinding;
    }
