HasSystemDecorations = false and then make your own header. Good example AvaloniaStudio

Windows with transparent areas aren't supported at the moment. On Linux/OS X it should be a fairly easy task, on windows it would be a bit complicated (UpdateLayeredWindow is slow, so this approach should be used instead, which in turn introduces compatibility issue, since WS_EX_NOREDIRECTIONBITMAP was introduced only in Win8).

I am also in need of this feature (to be able to port my application over correctly from WPF).
How does WPF handle transparent windows on Windows 7?

It appears that WPF uses WS_EX_LAYERED on Windows 10 even, so this talk about having to do WS_EX_NOREDIRECTIONBITMAP would be a straight upgrade from WPF.
