WCF Problem

Yuhnke posted on Tuesday, December 11, 2007

I have successfully implemented a client application using a csla library with remoting(Listener Service not IIS).
I am running in to a problem when trying to change the application over to WCF.

I have changed my client config to :

<appSettings>
    <add key="CslaAuthentication" value="Csla"/>
    <add key="CslaDataPortalProxy" value="Csla.DataPortalClient.WcfProxy, Csla"/>
    <add key="CslaSerializationFormatter" value="NetDataContractSerializer"/>
</appSettings>

    <system.serviceModel>
        <client>
            <endpoint name="WcfDataPortal"
                    address="net.tcp://blabla.blah:32784/WcfHost/WcfPortal.svc" binding="netTcpBinding" 
                    contract="Csla.Server.Hosts.IWcfPortal"/>
        </client>
    </system.serviceModel>

I have changed my server config to :

<configuration>
  <system.serviceModel>
    <services>
      <service
        name="Csla.Server.Hosts.WcfPortal"
        behaviorConfiguration="metadataSupport">
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://blablablah:32784"/>
          </baseAddresses>
        </host>
        <endpoint name="WcfDataPortal"
         address="net.tcp://blablablah:32784/WcfHost/WcfPortal.svc"
         binding="netTcpBinding"
         contract="Csla.Server.Hosts.IWcfPortal"/>
      </service>
    </services>
  </system.serviceModel>
 
  <appSettings>
    <add key="CslaAuthentication" value="Csla"/>
  </appSettings>

I am getting an error in the proxy.Fetch function on the svr.fetch***

public DataPortalResult Fetch(Type objectType, object criteria, DataPortalContext context)
    {
      ChannelFactory<IWcfPortal> cf = new ChannelFactory<IWcfPortal>(_endPoint);
      IWcfPortal svr = cf.CreateChannel();
      *****WcfResponse response =
        svr.Fetch(new FetchRequest(objectType, criteria, context));
      cf.Close();

      object result = response.Result;
      if (result is Exception)
        throw (Exception)result;
      return (DataPortalResult)result;
    }

The error I am getting is:

There was an error running this application, the error has been logged: System.InvalidOperationException: Cannot serialize the DataTable. DataTable name is not set.

This call happens to be a function retrieving a NameValueListBase.
 Any help would be appreciated.
