I have an Orchestration which contains a Long-running trasaction Scope
with an exception handler, that attempts to terminate the orchestration
via a Terminate shape.

I purposefully throw an exception from an external assembly component I
expose in a construct message shape of the scope.
Executing the orchestration gives me a number of the below error (note
there is NO looping retry, it should just execute it once and it
definately reaches the exception block of the scope):

Has anyone come across this, there is no mention of it on the net?

Still don't understand the exception but I figured out what caused it.
It was because my scope was long-running. Changed the scope's
transaction type to None, and it worked a treat.
