workflow foundation - Executing WorkflowInstance more then once -

If I have a workflow instance , can I execute twice in a row?

Workflow Instance Example = Turn on Workflow. Cretework Flow (typef (...)); Instance.start (); Instance.start ();

When I do this, I say and the exceptions tell me that I do not have persistence service configured though my question is that when I execute workflowinstance , Once an example can be run for another time, or does it become useless? Do I have to make another chance, when I want to execute?

According to the specifications of the workflow instance

take a look

< P> An invalid operation exception is thrown when the example is already running
