It works OK up to a point. There are traps everywhere. Some controls scale reasonably well, others don't. There is very little support for any vector drawing so you need to hand-roll resolution switching for assets (Admittedly, pixel based assets in WPF will require the same). Doing anything measure-based in code (rather than designer) such as placing items, requires remembering to manually multiply e.g. dpiScale * 16 to make a margin that will be 16px at 96DPI and 24px at 144DPI and so on. It eventually drives you insane.
