Use when releasing or publishing a WinUI app. Not for WPF, WinForms, or Electron apps that only reference the Windows App SDK.
winui-setupInstall and verify WinUI 3 prerequisites — .NET SDK 8.0.100+, WinApp CLI 0.7+, and Developer Mode; identify additional Native AOT and Windows Sandbox requirements. Use when the user asks to set up or repair the toolchain, or when another WinUI skill finds a missing or outdated prerequisite.
