The workflow definition of the workflow to invoke.
The following example invokes a workflow consisting of a single DiceRoll activity. The DiceRoll activity has two output arguments that represent the results of the dice roll operation. When the call to Invoke returns, each output argument is returned in the outputs dictionary, keyed by argument name.
If the workflow's root activity has no output arguments or they are not needed by the host, they can be disregarded. The following example invokes a workflow consisting of a single WriteLine activity that does not have any output arguments.
