You can use the same database, but in Beta1 they use different tables. This is all fixed in Beta2

Are you saying that you can only have persistence for either WorkflowServiceHost or WorkflowInstance in a particular database?

Correct, we don’t let you dynamically create children as part of the same workflow. That said, this restruction was in place for 3.5 as well. If you want to send me the 3.5 and 4.0 code offline, I can take a quick look. The recommended approach for such a dynamic case is to use a separate workflow, and depending on your persistence needs, you can either use WorkflowInvoker.BeginInvoke(), or a service boundary to execute the dynamic workflow.
