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 the WinRT XAML framework 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|last=Blog|first=Windows Developer|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/|access-date=2021-05-28|website=Windows Developer Blog|language=en-US}}</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.

==Windows Phone==

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

In [[Windows Phone 8.1]] the Windows RuntimeWinRT 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]] based XAML apps and new features and API were also added to this framework too (called [[Silverlight]] 8.1<ref>{{cite web |url=https://msdndocs.microsoft.com/en-us/libraryprevious-versions/windowsphonewindows/developapps/dn642082(v=vs.105) |title=Windows Phone Silverlight 8.aspx1 apps |department=Windows 8 development |website=[[Microsoft Docs]] |date=May 20, 2016 |access-date=2021-10-15}}</ref>)

==Related technologies==

The XAML FrameworkWinUI is related to [[Windows Presentation Foundation]] (WPF) and [[Silverlight]] (WPF/E)—similar XAML-based UI frameworks used for desktop applications and portable applications respectively. The XAML frameworkWinUI uses a lot of the same names for its APIs as both of these older technologies—especially Silverlight, but its use is limited to the Windows OS (specifically Windows 8 and later) as with WPF. The major difference is that SilverlightWPF and WPFSilverlight are largelywritten based on thein [[CommonC LanguageSharp Runtime(programming language)|C#]] (CLR) and as such require using programming[[.NET languageslanguage]]s such as [[C Sharp (programming language)|C#]] or [[Visual Basic .NET|Visual Basic]], while theWinRT XAML framework is part of the Windows Runtime, written in [[C++]] and available to [[machine code|native code]] and also available, and has tools for development, with [[C++/CX]] or [[C++/WinRT]].
