从WF 4.0中的持久性存储加载工作流实例时获取当前活动

Question

I've still been trying to wrap my head around some workflow issues we've been having. I'm using Workflow foundation 4.0 and I need to get the current activity of an instance when I load it from persistence. I tried using tracking, but that does not get called when the instance is loaded.

I'd like to avoid having to persist this information myself if at all possible.

Do you have any idea about how to do this?

As far as I know using tracking is the only way to monitor which activity starts and stops. Using a workflow extension deriving from PersistenceParticipant you can save the data as part of the workflow itself. Keep in mind that the could be multiple active asynchronous activities when a workflow is persisted.

See this question for how to do so.
