It enables declaring user interfaces using [[Extensible Application Markup Language]] (XAML) technology.

WinUI is one of the multiple UI frameworks provided built-in for the Windows Runtime; the others being [[HTML5]] (e.g., via [[WinJS]]) and [[DirectX]].

WinUI 2 is an extension library for UWP XAML containing controls and styling that match the Windows 11 design language. It is shipped through NuGet and is distinct from the UWP XAML framework, which provides the actual rendering engine; though, they may be treated as synonyms.

WinUI 3 decouples WinRT XAML from the operating system as a separate package to be updated quickly and make new features work on older versions of Windows.<ref>{{cite web |first=Miguel |last=Ramos |date=2020-07-07 |title=A deep-dive into WinUI 3 in desktop apps |url=https://blogs.windows.com/windowsdeveloper/2020/07/07/a-deep-dive-into-winui-3-in-desktop-apps/ |department=Windows Developer |website=Windows Blogs |access-date=2021-05-28}}</ref> It is part of [[Windows App SDK]] (codenamed "Project Reunion"), a Microsoft effort to reconcile the Windows desktop (Win32) and the UWP low IL app model.

Line 37 ⟶ 40:

Up to [[Windows Phone 8|Windows Phone 8.0]] WinRT XAML was not supported and XAML applications were based on [[Silverlight]] XAML and deployed in [[XAP (file format)|XAP]] format.

In [[Windows Phone 8.1]] WinRT XAML is available along with improved Windows Runtime support. This convergence between platforms enable [[Universal app]]s that can target both Windows 8.1 and Windows Phone 8.1 while sharing most of the code, including user interface. The [[Windows Phone 8.1]] is still capable of running [[Silverlight]] XAML apps and new features and API were also added to this too (called [[Silverlight]] 8.1<ref>{{cite web |url=https://docs.microsoft.com/en-us/previous-versions/windows/apps/dn642082(v=vs.105) |title=Windows Phone Silverlight 8.1 apps |department=Windows 8 development |website=[[Microsoft Docs]] |date=May 20, 2016 |access-date=2021-10-15}}</ref>)
