Async Passive State Machine

The AsyncPassiveStateMachine is a state machine that supports async/await for transition actions, entry/exit actions, guards and save/load. Like the PassiveStatemachine it performs transitions on the same thread as the code calling the state machine. That means that when the call to Fire returns to the caller and the returned task is awaited then the transition is performed.

State Machine Events Execution

All events fired onto the state machine are executed on the same async/await chain as the caller.

Actions queueing events

When a transition, exit or entry action fires an event onto the state machine then this event is executed immediately after the initial event is processed and before task returned by Fire is completed.
