About this tag
The tag uwp vs winui covers discussions comparing Universal Windows Platform (UWP) and Windows UI Library (WinUI) development frameworks, particularly in the context of Windows app performance. A recent thread highlights how Meta replaced its native UWP WhatsApp client with a Chromium WebView2-based wrapper, leading to excessive RAM usage of up to 1.2GB after login.
