>Has anyone used the new VFP60 foundation classes in developing a significant product that they have deployed? We are considering using these for a major development effort and would like to hear any feedback regarding how robust the classes are, if they require more overhead than anticipated, how are they on performance, how extensive any customization may have been and generally any comments. Thanks much in advance for any information you can provide.

If you can get ahold of recent Foxpro Advisor issues, Miriam Liskin has written a few articles on using the VFP6 framework.
