there are some custom SystemBackdrop which you can use in your app:
MicaBackdrop Example 1 Window.SystemBackdrop = new MicaBackdrop() { Kind = MicaKind.Base };
or
1 2 3 4 5 6 <Window ... xmlns:dev ="using:DevWinUI" > <Window.SystemBackdrop > <dev:MicaBackdrop /> </Window.SystemBackdrop > </Window >
AcrylicBackdrop 1 AcrylicBackdrop : SystemBackdrop
Example 1 Window.SystemBackdrop = new AcrylicBackdrop() { Kind = DesktopAcrylicKind.Base };

1 Window.SystemBackdrop = new AcrylicBackdrop() { Kind = DesktopAcrylicKind.Thin };
or
1 2 3 4 5 6 <Window ... xmlns:dev ="using:DevWinUI" > <Window.SystemBackdrop > <dev:AcrylicBackdrop /> </Window.SystemBackdrop > </Window >
if you use Acrylic or Mica Backdrop, you can change backdrop config with: ConfigBackdropTintColor, ConfigBackdropFallBackColor, ConfigBackdropTintOpacity and ConfigBackdropLuminosityOpacity
TransparentBackdrop 1 TransparentBackdrop : SystemBackdrop

CompositionBrushBackdrop you can use CompositionBrushBackdrop
