If Microsoft were serious about 'low code' we would be looking at Visual Basic 7.
There was a Visual Basic 7. The current compiler for "Visual Basic 2019" is version number 16.0 and the version numbers carry directly through. The VB team moved on, even if if so many of the users didn't. You can get pretty RAD with WinForms (or WPF) on .NET 5 with VB in Visual Studio right now today. It's not the same ActiveX mess of the 90s but that's a good thing in its own way.
