A couple of months ago, we posted a new sample on our community site which is based on the UServ Product Derby scenario showcased at the Business Rules Forum. At the webcast a few weeks back, I briefly mentioned this sample as one that showcases a lot of our extensibility points and I got a few queries about it which I thought I'd clarify.
The sample we have posted is demonstrating the following things -
Most vendors who participate in showcasing this at the Business Rules Forum are showing their business analyst capabilities - they're showing how to model this solution using their suite of products.
One of the webcast attendees was confused as a result after he looked at our sample. The sample is demonstrating technical feasibility and is a starting point for an ISV or developer who wants to leverage the WF Rules Engine and the .NET Framework and build richer experiences. It is not trying to showcase WF Rules as an out of box business analyst experience. The sample re-uses the RuleSet editor which is a developer UI for authoring rules and is available in the .NET Framework 3.0.
