workflow - Beginner WF4 question - When is WF4 useful, really? -

if want use traditional approval type workflow in regular asp.net system, example order needs approval before order placed. rather having traditional enum orderstatus, can benefit using microsoft wf4 (workflow version 4) or generate more complexity , more code no added benefit?

any time have long running operation wf4 possibility. fact graphical designer allows show actual running process, not visio copy of it, huge benefit.

there learning curve wf4 , there times have things wf4 way instead of c#/vb way did before. said there benefit, thinks approval request not being handled in, lets say, 14 days easy in wf4.
