Aforge is not even close to Infer.NET. The latter is a library to build graphical models and automatically generate deterministic inference algorithms for them. Trust me when I say there are probably less then 25 people in the world that can derive some of these inference algorithms without spending weeks studying the relevant papers (e.g. EP). Aforge is just a collections of algorithms. It's nothing to do with building your own models. Useful nonetheless.
