echo WCF LOB Adapter with BizTalk RRS feed

  • Question

  • I am trying to connect the echo adaptor (provided in the WCF LOB SDK). However I am getting the following error when I am sending an EchoString action to the adaptor

    The adapter failed to transmit message going to send port "WcfSendPort_EchoAdapterBinding_EchoOutboundContract_Custom" with URL "echov2://lobhostname/lobapplication?enableAuthentication=False". It will be retransmitted after the retry interval specified for this Send Port. Details:"Microsoft.ServiceModel.Channels.Common.AdapterException: Cannot resolve metadata for operation identifier <BtsActionMapping xmlns:xsi="" xmlns:xsd="">

    <Operation Name="EchoStrings" Action="Echo/EchoStrings" />
