Fullscreen not working on macOS or Linux

I have a very simple app that I want to run full screen. I can’t seem to get it to work on either my mac dev machine or the linux (raspberry pi) machine that I am running it on.

WindowState="Maximized"

and setting

this.HasSystemDecorations = false;
this.WindowState = WindowState.Maximized;
this.Topmost = true;
this.WindowStartupLocation = WindowStartupLocation.CenterScreen;

On the MainWindow.xaml(.cs) doesn’t seem to work at all. It does hide system decorations and jump to the screen, but it’s not fullscreen.

The Fullscreen option doesn’t show up in the possible choices for me and even if I set it, it doesn’t compile.

It’s only in pre-release at this point.

For now you can copy-paste SendNetWMMessage and required classes and use it like this. XID is available via this.PlatformImpl.Handle.Handle.
