NJDX is an amazingly simple and intuitive OR-Mapper. I'm extremely impressed with just about every facet of it.
NJDX is powerful, flexible, easy-to-use, performant, reliable, and most importantly, it fits seamlessly into any architectural model.
And few times in my career have I seen such a committed and passionate group of professionals. There is no detail too small for them to address if it means building an excellent product and putting a smile on their customer's faces.
