I doubt very seriously that etecnologia will be able to take full advantage of all that .net offers using VFP as the source...,

You may be correct, but what are you basing that on? Are you just describing your belief system or have you actually investigated?

Will it write WPF apps? Silverlight? I think it'll be handicapped out of the shoot and very few people will use it.

That's a curious question from an MVP for device application development. ;-)

Basically the compiler is written in VFP then compiled using itself. AFAICS there is no reason why the compiler can't compile a scx as WPF rather than as a Winform or anything else for that matter. The first time I saw that done in VFP was ? 10 years ago when Rick Strahl produced a DHTML renderer that did a pretty good job of rendering a VFP form for a browser including working buttons and data-aware controls that automatically handled round trips to the server. AFAICS the same VFP code/scx may be compiled to multiple different systems including the new NET5.0 Netbluey GUI that isn't available yet. Not sure whether you can say the same for your own work. ;-)
