How to assign IWorkflowTask to a workflow?

[defunky]

Is it possible to create a new WorkflowTask and assign it to a new workflow? The docs aren't very descriptive, I can see that you can call the CreateWorkerHost to execute that specific task but how can I use it with ConductorWorkflow.WithTask method? I've tried passing in new WorkflowTask with the name of the IWorkflowTask type assigned but this doesn't seem to work, am I missing something?
