title: Windows Workflow Foundation in modular application
body: <p>I have a question about WWF, I'm working on a webbased ERP project which is a modular application ofcourse.
  I'm looking for a way to create an engine for wokflows in the framwrok so modules can rely on it and based on this engine create their workflows.As I see there should be 3 kind of workflows (Human for confirmation of info among the organization, Business for handling business flows such as calculating personnel income based on the different factors and UI workflow for handling chain of usercontrols based on a cartable (dashboard) )
  I need some help on handling this and if there is any problem in my insight I wonder to be informed.</p>
