Enumerate possible states transition of Workflow Foundation state machine.

Question

For GUI purposes I need by current state of state machine to enumerate possible available states of transition. For example there is transitions: A->B, A->C, B->D, C->D. Assuming state machine is in A state, so I need get list of B and C.

Answer 1

I've found my own answer, right now it looks as stupid question. So, it is enough to create lightweight object StateMachineWorkflowInstance around my instance of Workflow, here the code:

StateMachineWorkflowInstance smw =
            new StateMachineWorkflowInstance(MyWorkflowRuntime, A);
return smw.PossibleStateTransitions.ToArray();
