You need to start somewhere. I started with VPM, and switched to Mere Mortals myself. I looked at the base framework from VFP, and thought I wanted/needed a better starting platform.

What components are you interested in? Data, n-tier flexibility, COM, UI, WEB, Reports,....? Maybe if I had more info I could see where you are going towards?

I agree that all the products are tightly coupled, hence they do a good job within their respective FW's.

>Codebook is a fairly tightly coupled standard. In essence it is a framework -- but a public domain one. That is there are certain properties your classes are expected to have with particular names, certain methods with particular names, a particular class hiearchy. Kevin M's Mmortals framework is based on codebook, but with greatly enhanced flexibility and power. His abstract factory enhances this flexibility -- but contains some tight coupling. The tight coupling is not a flaw -- a framework by its nature IS tightly coupled.

One way it could work would be to create some sort of framework consortium and achieve a consensus on component interfaces and behaviors. Components could then be swapped and it wouldn't matter who developed the component(s) as long as they abide by the standards. Actually, this could be a boon to the VFP community.
