BizTalk Tip of the Day: If you’re writing a custom BizTalk Pipeline
Component (particularly a receive one), and you’re creating a new message from scratch
to return from your component, don’t forget to copy the original message context into
your new one.
And the right way to do this is using the CloneMessageContext() method
of the PipelineUtil helper class included with BizTalk. Rolling your own and doing
it incorrectly can result in really weird errors later on.
