 // When Position is Manager then MDate is required
BusinessRules.AddRule(new ConditionRule<Required, string>(
                              PositionProperty, (p) => p == "Manager"
                             ,new Required(MDateProperty)));

 // When Position is not Manager then EDate is required
BusinessRules.AddRule(new ConditionRule<Required, string>(
                              PositionProperty, (p) => p != "Manager"
                             ,new Required(EDateProperty)));
