Icon not set on WinUI window

[nickrandolph]

The .ico file is being created for WinUI but isn't being set on the ApplicationIcon property, so results in the default icon

I tried to add the ico file directly to the project, so the Resizetizer will not handle that... And the icon didn't show on window. So I'm wondering if there's one more step, on winUI itself, to make that ico visible.

<PropertyGroup>
		<ApplicationIcon>iconapp.ico</ApplicationIcon>
</PropertyGroup>

here's the branch with the change
