System.ServiceModel.CommunicationException

Question

I am using WCF client server. The WCF Server ist installed on a terminal server. When I am testing it locally everythings work with a local WCF Server.

An unhandled exception of type 'System.ServiceModel.CommunicationException' occurred in mscorlib.dll
Fehler beim Deserialisieren des Textkörpers der Antwortnachricht für Vorgang "MixGas". Es wurde das Endelement "MixGasResult" aus Namespace "http://tempuri.org/" erwartet. Gefunden wurde "Element "b:GasMatrice" aus Namespace "http://schemas.datacontract.org/2004/07/RadaxPpdsLibrary"".

I do not know what I shall do. The call ist the following:

   public string MixGas(double incomingMassFlow, string incomingGasInp, double sideMassFlow, string sideGasInp,
        out double outgoingMassFlow, out string outgoingGasInp)
    {
        var result = Channel.MixGas(incomingMassFlow, incomingGasInp, sideMassFlow, sideGasInp,
            out outgoingMassFlow, out outgoingGasInp);

        return result;

    }

The method Channel.MixGas raises this exception. I am using other server methods without any exceptions.

This server config file is:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup>
  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
              switchValue="All"
              propagateActivity="true">
        <listeners>
          <add name="traceListener"
               type="System.Diagnostics.XmlWriterTraceListener"
               initializeData= "Traces.svclog" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>
</configuration>

This is the server configuration in C#:

   serviceHost = new ServiceHost(typeof(RadaxPpdsServerLibrary.RadaxPpdsService));

     var binding = new NetTcpBinding()
    {
        OpenTimeout = new TimeSpan(0, 10, 0),
        CloseTimeout = new TimeSpan(0, 10, 0),
        SendTimeout = new TimeSpan(0, 10, 0),
        ReceiveTimeout = new TimeSpan(0, 10, 0),
        MaxReceivedMessageSize = 1000000,
        MaxBufferSize = 1000000,
        MaxConnections = 100,
        Security =
        {
            Mode = SecurityMode.None,
        }
         // PortSharingEnabled = true
     };

    serviceHost.AddServiceEndpoint(typeof(IRadaxPpdsService), binding, "net.tcp://localhost:60000/RadaxPpdsService/RadaxPpdsEndpoint");

Enable wcf tracking to find internal exceptions and view specific error messages. Here is the reference of enable wcf trace: https://stackoverflow.com/questions/4271517/how-to-turn-on-wcf-tracing — Theobald Du, Jul 09 '21 at 02:17
I have added this tracing method now I am confused. I get the erorr in error.svclog The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '10675199.02:48:05.4775807'. But the client does not raise any exception. — ora, Jul 12 '21 at 08:31
After adding MaxBufferSize = 1000000, to client the socket connection abort has gone away. The System.ServiceModel.CommunicationException error is still an there. — ora, Jul 12 '21 at 09:06
It works now I have explicitely maxItemsInObjectGraph to 2147483647. It works. Thanks. — ora, Jul 21 '21 at 10:15

if you post your config file , it would be great , without your config file it's so hard to find the problem.
