Visual studio\code intellisense experience

[Chrys4lisfag]

Decided to take a look at the framework and experienced some issues with VisualStudio (both MSVC\Clang) and Visual Code IDE.

After the first adapter intellisense has issues in guessing the return type which makes developing inconvenient or mostly impossible. The code compiles just fine but no type guessing, so not possible to look for methods etc.

As I understand this is purely intellisense issue but does anyone know of a way to fix this?
