currently i'm involved in project lots of rules in it. there's idea use biztalk's business rule composer rule creation. question1. possible use independently? question2. if so, how can subscribe change of different fact source types .net objects , databases ? fyi, i'm using biztalk server 2013. well, run rules composer need have biztalk engine installed, can't separate them, in such case end pay license of biztalk have rules engine composer. why not use product? think there products concerned business rules engines can use , workflow well. if want free 1 can have worlflow 4.0 microsoft (doesn't include business rules engine can implement 1 using specification pattern - code). other paid products such k2 blackpearl might check them out.
