Sort of. It uses Win32's windowing and input/message loop primitives for top-level windows but within a window's content all the layout, controls and rendering are WPF-bespoke. This is different from Windows Forms which wraps Win32 controls. It's also different from UWP/WinUI which can use Win32 windowing primitives, but doesn't necessarily depend on them. This is all using Win32 to refer specifically to the UI side of things, but if we use "Win32" to refer to the entire set of flat C-style Windows APIs then all these frameworks are heavily dependent on Win32

It is. It’s based on DirectX. I think version 9.
