Michael Maurer's List: Regelbasierte Komponenten .Net

"Revolutionary web interface. By using the Web Rule business rules engine, any educated adult can write complex rules simply by selecting rule elements from the context-sensitive menu. The end result literally looks like a spoken sentence: If customer home state is Georgia then add no shipping cost else add shipping (9.95). No IT personnel are required to author business rules and no code re-compilation is needed if rules are modified."

"NxBRE is a lightweight Business Rule Engine (aka Rule Based Engine) for the .NET platform, composed of a forward-chaining inference engine and an XML-driven flow control engine. It supports RuleML 0.9 Naf Datalog and Visio 2003 modeling."

"The Drools.NET is a .NET port for Drools, which is a java Rules Engine based on Charles Forgy's Rete algorithm. Drools.NET enables .NET developers/Users to exploit the powerful Rule Engine like Drools through a completely managed .NET code base."
