There is no guarantee. While compatibility has always been high on the Windows feature list, at some point it will have to be sacrificed to move on. Seeing as almost no information about the successor to Vista is coming out of Microsoft, it's impossible to tell what level of compatibility will exist in the future.
>(My apologies if this has been discussed already). Can somebody shed some light on just what it means that VFP will no longer be supported after 2015? In particular, when the product is no longer "supported", does it mean that Microsoft gives itself license for incompatibility? Is MS saying that beyond 2015, it might produce versions of Windows no longer compatible with existing VFP apps, so that apps created today with VFP8 or VFP9 would essentially no longer be usable?
