         I think I found a reson for the necessity of the WCF-Custom adapter.
        We are processing large amounts of complex data, and we were getting the error “Connection closed unexpectedly”.
        By doing a service side trace, we learned that the real message was:
        ‘Maximum number of items that can be serialized or deserialized in an object graph is ‘65536’. Change the object graph or increase the MaxItemsInObjectGraph quota. ‘. 

         

         

         

         

         

         

        In C# client, the solution was to add this XML to the app.config (and similar to web.config).
        <

        behaviors>
          <        endpointBehaviors>
              <        behavior name=“LargeEndpointBehavior“>
                  <        dataContractSerializer maxItemsInObjectGraph=“10000000“ />
              </        behavior>
          </        endpointBehaviors>
        </        behaviors>

        I used the import function to get this into a custom pipeline, but then still got the same message.
        Has anybody been down this road before?

        Thanks,
        Neal Walters

          From your post, it sounds like BizTalk is acting as a client in this scenario.  Did you apply the behavior on the service side as well?

               You need to  set the maxReceivedMessageSize attribute on the http transport bindings. This can be done using the receive location config UI.

                   I set the maxReceivedMessageSize a long time ago.  This is a totally new error related to the size of the “object graph”.

                  I did create a custom port.  There was a button on the last tab to import an app.config, which I did, and it set up the parm on the custom config tab.  However, it still didn’t work – I need to test more as soon as I deal with higher priority issues.
