MS Workflow Foundation 4 - Can the workflow model be interigated at runtime, as in to generate a visual representation of it?

can the workflow model be interigated at runtime. Reas开发者_如何学运维on, to generate a visual web representation of it? For highlighting the current node of the workflow, for example.

If you want to check on the activity tree the WorkflowInspectionServices will help you do that.

I found this link about dynamically changing workflows, which would imply that the workflow can be interrogated at runtime. http://community.bartdesmet.net/blogs/bart/archive/2006/08/28/4322.aspx
