Hi,
Sorry, although it is called “Visual Studio”, it is a completely different product based on a different technology stack. So “extending” VisualGDB to support it would require rewriting it from scratch using a different technology. As of today we don’t have such plans, sorry.
That said, Microsoft is working on a GUI framework that will support building modern cross-platform GUI using the .Net technology, so we might be able to support Visual Studio for Mac and Visual Studio code once this framework matures.
