BAM Activity in Custom Pipeline

Sometimes requirement cannot be fulfil by using tracking profile editor for BAM logging. Here in this code I am explaining about how to use BAM in custom pipeline. And also I am using EnableContinuation method so that we can get all the details in single row in BAM table while using different stage of BAM tracking in BizTalk application. When a solution needs BAM, and you what to link the receivedTime and sendTime together you have to use continuation.

Code for BAM Activity in Custom Pipeline:

Begin BAM Activity

This custom pipeline component can be put after xml or flat dissembler pipeline component in Receive Pipeline, because we are consuming MessageType context property to log into BAM.
