NxBRE 3.0 Released

"Finally, after weeks of refactoring, a general beefing up of the documentation, version 3.0.0 is officially out! Check the readme file for discovering the extent of what has been done between version 2.5 and version 3.0. ..."

This is one of those projects I keep thinking that I'll need one day...

Yes, there may be some overlap with Windows Workflow (WF), but NxBRE is out today, includes the source (OSS license = LGPL), is simpler to deploy (i.e. xcopy, etc) and is a little more mature (It's a v3! ;)

Just a reminder as to what NxBRE is (http://nxbre.org);

"NxBRE is the first open-source rule engine for the .NET platform and a lightweight Business Rules Engine (aka Rule-Based Engine) that offers two different approaches:

the Inference Engine, which is a forward-chaining (data driven) deduction engine and that supports concepts like Facts, Queries and Implications (as defined in RuleML Naf Datalog sub-language) and like Rule Priority, Mutual Exclusion and Precondition (as found in many commercial engines). It is designed in a way that encourages the separation of roles between the expert who designs the business rules and the programmer who binds them to the business objects.
the Flow Engine, which uses XML as a way to control process flow for an application in an external entity. It is basically a wrapper on C#, as it offers all its flow control commands (if/then/else, while, foreach), plus a context of business objects and results. It is a port of JxBRE v1.7.1 (SourceForge Project from Sloan Seaman) to .NET's Visual C#.

NxBRE 's interest lies first into its simplicity, second in the possibility of easily extending its features by delegating to custom code in the Flow Engine or by writing custom RuleBase adapters or Business Objects binders in the Inference Engine.
