Using rules for page flow is a common question on our internal discussion aliases and in the WF forums. We're happy to share that Kushal Shah, a tester on the Rules team, has just posted a sample on the community site which uses rules (standalone, that is, without WF) in an ASP.Net application to drive page flow. The sample shows how rules can be used standalone in driving the page flow and the business logic for an ASP.Net application.
