[SOLVED] WCF Error "Maximum number of items that can be serialized or deserialized in an object graph is '65536'"

WCF Error "Maximum number of items that can be serialized or deserialized in an object graph is '65536'"

I am receiving the following error on a WCF call:

Maximum number of items that can be serialized or deserialized in an object graph is '65536'

I've read a ton of forum posts and many of them mention modifying the app.config and web.config to specify new behavior to allow larger object graphs. I've done that and this is what I have in those files:

App.Config on the WPF project:

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="">
      <serviceMetadata httpGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="">
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
    </behavior>

  </endpointBehaviors>

</behaviors>

<services>
  <service name="digiPM.Shell.LogOutPMSEMRService.PMSEMRLogOutService">
    <!--<endpoint address="" binding="basicHttpBinding" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" />
      </baseAddresses>
    </host>-->
    <endpoint address="" binding="netTcpBinding" name="NetTcpBindingEndpoint" contract="digiPM.Shell.LogOutPMSEMRService.IPMSEMRLogOutService">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="MexTcpBidingEndpoint" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8732/Design_Time_Addresses/digiPM.Shell.LogOutPMSEMRService/PMSEMRLogOutService/" />
      </baseAddresses>
    </host>
  </service>
</services>

<!--binding info - removed this for the sake of readability for this post -->

web.config on the service project:

<system.serviceModel>

<bindings>
  <wsHttpBinding>
      <binding name="WSHttpBinding_Services" closeTimeout="01:10:00" openTimeout="01:10:00" receiveTimeout="01:10:00" sendTimeout="01:10:00" bypassProxyOnLocal="false" 
               transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" 
               messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false">
          <readerQuotas maxDepth="4096" maxStringContentLength="2147483647" maxArrayLength="524288" maxBytesPerRead="524288" maxNameTableCharCount="524288" />
          <reliableSession ordered="true" inactivityTimeout="01:10:00" enabled="false" />

          <security mode="None">

          </security>
      </binding>
  </wsHttpBinding>
</bindings>

<behaviors>
  <serviceBehaviors>
    <behavior name="digiPM.Service.Behavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />
    </behavior>

  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="customObjectQuota">
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
    </behavior>
  </endpointBehaviors>
</behaviors>

<services>
  <service behaviorConfiguration="digiPM.Service.Behavior"
    name="digiPM.Service.AddressCrudService">
    <endpoint address="" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_Services"
                name="AddressCrudServiceEndPoint" bindingNamespace="urn:Dawliasoft.Sculpture"  contract="digiPM.Services.Contracts.IAddressCrudService" behaviorConfiguration="customObjectQuota" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"  behaviorConfiguration="customObjectQuota" />
  </service>

 <!--<more services defined with same configuration as above..>-->

  </services>


</system.serviceModel>

This, however, hasn't helped. Note that the services referenced in the APP.CONFIG are not the services I am having issues with.

I've also tried the following:

added these attributes to the service implementation: [DataContract(IsReference=true)], [ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, MaxItemsInObjectGraph = 2147483646)]
wrote a custom DataContractSerializerOperationBehavior class that set MaximumObjectsInGraph and IsReference behavior. Also added custom Attribute to apply this the service implementations. For the sake of clutter, I didn't post the code, but can add it if anyone thinks it would be beneficial.

Thoughts? Ideas? Where do I go from here?

Thanks in advance!

Solution

I just realized that your WPF config file is not right. So, I deleted all my comments because they were assuming a valid WCF configuration. Your WPF config file is not right ... it needs to say "Client" instead of service ... Are you using "Add Service Reference" in Visual Studio? if so, it should have created the correct config file for you.

Otherwise, please refer to MSDN for the correct format for your client config file in your WPF project.
