I think you're getting caught up in semantics again. VFP has a form of multithreading when called from a multithreaded client and C# has a more efficient form of multithreading. But they're both calling multiple threads at the same time. I think saying VFP has no multi-threading capability at all is doing more harm than good since developers may assume from this that vfp will not perform well as a web app, for example...
