Hi,
I'm having a problem where Stateless is not catching any undhandled exceptions. Say I want to throw an error in one of the steps; how would I handle it outside the steps itself? Current in RELEASE compilation it even gives me a BSOD?

In debug mode i find it throws the exception on this but i dont seem to find a way to handle it (unless I handle it in Step10 function):
.OnEntry(async x => await Step10())

Would appreciate your feedback.

Have you tried using the .OnEntryAsync method call instead of OnEntry, and use FireAsync when transitioning. (where you normally use Fire) - this could be the root of your issue.

You could also have a look at the OnUnhandledTrigger/OnUnhandledTriggerAsync to create your own behavior for exceptions, i believe. (havent tested it)

I have not tried those methods yet. The OnHandledTrigger I'm using but I believe that fires only on undefined triggers.
