Custom Window Pointer in Windows (I don't know a correct name for this)

[PieroCastillo]

Hello, I found a simple way to render Graphics in Windows Desktop Background, and now I want to use it for Avalonia Win32, but I don't know a way to put a custom window pointer (and I don't know if that is possible), so, what u think? I want to do this for a Wallpaper App

I don't think that any UI toolkit allows wrapping externally managed window handles. But you can try implementing your own ITopLevelImpl and use EmbeddableControlRoot for hosting your content.
