Hi Suresh,
Whenever you are doing request-response like calling web service etc, i would suggest to use Passthrough pipeline while sending and use XML receive for receiving the message.
Because when you are sending the message out it doesn't needs any promoted properties so you can use Passthrough this will avoid extra Assembling/Validation etc tasks performed by XMLSend pipeline.
But when you are receiving response that time it expects MessageType property to be promoted because normally you will have receive shape configured to some Typed Schema. So you will have to use XML Receive pipeline.
Thanks,
