Cannot pass a GCHandle across AppDomains

Question

Hi everybody,

I have implemented quickfix engine using asp.net and C#. and i am calling quickfix_net.dll which is written in unmanaged C++. but i am getting error like "Cannot pass a GCHandle across AppDomains" when calling quickfix_net.dll.

but the same thing is running in console application but not under IIS i.e asp.net

please anybody look into matter. thanks in advance

Following are my code:

SessionSettings settings = new SessionSettings(tradeClientPath);

                ApplicationMessage application = new ApplicationMessage();
                FileStoreFactory storeFactory = new FileStoreFactory(settings);
                FileLogFactory logFactory = new FileLogFactory(settings);
                MessageFactory messageFactory = new DefaultMessageFactory();

                SocketInitiator initiator = new SocketInitiator
                  (application, storeFactory, settings, logFactory, messageFactory);
                initiator.start();

                Message message = new Message();

                OrdType ordType = new OrdType(OrdType.MARKET);

                QuickFix42.NewOrderSingle newOrderSingle = new QuickFix42.NewOrderSingle(new ClOrdID("1"), new HandlInst('1'), new Symbol("WAKEN\00110048=2")
                                  , new Side(Side.BUY), new TransactTime(), new OrdType(OrdType.MARKET));

                newOrderSingle.set(new OrderQty(10));
                newOrderSingle.set(new TimeInForce(TimeInForce.DAY));

                Message.Header header = newOrderSingle.getHeader();
                header.setField(new SenderCompID("CLIENT1"));
                header.setField(new TargetCompID("EXECUTOR"));

                message = newOrderSingle;

                **QuickFix.Session.sendToTarget(message);** // here i am getting exception

                initiator.stop();
