>True, but still as quoted directly from his white paper, "Apartment model threading provides a simulation of multi-threading, but does not really make an application truly multi-threaded and reentrant at the binary level as a C++ program."

VFP can't generated free-threaded COM objects; neither can VB, and unless you're careful in coding it, not all C/C++ objects are, either. From a proactical perspective, unless you have asynchronous operations taking place with callbacks and spawning of multiple threads within the COM object, free-threading doesn't buy you a great deal.
