Jurgen Willis’s very good article on “Introduction to the Windows Workflow Foundation Rules Engine

Rules technology is exposed in two key ways in WF—as conditions on activities and as a forward chaining RuleSet in the Policy activity.

Activity conditions include IfElseBranch – While – Replicator and ConditionedActivityGroup (CAG)

The Policy activity encapsulates the definition and execution of a RuleSet. A RuleSet is a collection of rules with a set of execution semantics. Rules are, in turn, If-Then-Else expressions that operate on the workflow members.

Forward chaining is a very powerful notion that allows atomic rules to be assembled into RuleSets without the definition of, or necessarily even the knowledge of, the dependencies among the rules.
