WinUI About WinUI · Documentation · Release notes WinUI is a user interface layer that contains modern controls and styles for building Windows apps. The current generation is WinUI 3, which ships as part of the Windows App SDK. Modern UI: WinUI embodies Fluent Design to enable intuitive, accessible, and powerful experiences and the latest user interface patterns. Developers in control: Use .NET with C# or C++ to write apps that run great on x86, x64 and ARM. Optimized for modern experiences & hardware: Create performant experiences with WinUI that are optimized for modern hardware. Part of the Windows App SDK: The Windows App SDK is a set of libraries, frameworks, components, and tools that you can use in your apps to access powerful Windows platform functionality from all kinds of apps on many versions of Windows. The Windows App SDK combines the powers of Win32 native applications alongside modern API usage techniques, so your apps light up everywhere your users are. Powers key experiences in Windows: Windows experiences and apps are built with WinUI. Its rich control set and styles make it easy to develop high-quality experiences used by millions every day. 📋 Getting started with WinUI For WinUI, your app's users must be on Windows 10 1809 - Build 17763 or newer (including Windows Insider Previews). The full documentation of WinUI can be found on Microsoft Learn: Get started with WinUI Build your first WinUI app Migrate from UWP to the Windows App SDK Windows Runtime APIs not supported in desktop apps WinUI & Windows App SDK samples 🖼️ WinUI 3 Gallery Make sure to also check out the WinUI 3 Gallery, our interactive sample experience showing everything you can do with WinUI. 📺 WinUI Community Call The WinUI Community Call is your opportunity to learn about WinUI and to engage with the WinUI team and community. Join us online on YouTube at the Windows Developer channel. 📢 Contributing to WinUI The WinUI team welcomes your feedback! To understand how we handle incoming feature requests and bugs, please see our contribution handling guidelines. For information on how to contribute, please see Contributing to WinUI. WarningWe're not yet ready to accept code contributions, but we are working towards that goal. It is now possible to build the WinUI product binaries, with work in progress to share test code and enabling locally running tests. To get started building WinUI from source and see more details on current limitations, see Getting started with building WinUI. See the WinUI OSS Update post to check the latest status. For the latest code and updates, use the main branch. 🛣️ Roadmap For info on the WinUI release schedule and high level plans please see the WinUI roadmap. 🔧 WinUI for UWP WinUI for UWP (WinUI 2) is a library of controls that provides Microsoft UI controls and features for UWP apps. Learn more about WinUI for UWP here or download the source code here. You can get the WinUI 2 Gallery on the Microsoft Store and see the source code here.

Anything related to WinUI is a bad joke. Have fun following the discussions and amount of bugs, https://github.com/microsoft/microsoft-ui-xaml That C++ support that WinUI team marketing keeps talking about relies on a framework that is no longer being developed. > The reason the issues page only lets you create a bug report is because cppwinrt is in maintenance mode and no longer receiving new feature work. cppwinrt serves an important and specific role, but further feature development risks destabilizing the project. Additional helpers are regularly contributed to complimentary projects such as https://github.com/microsoft/wil/. From https://github.com/microsoft/cppwinrt/issues/1289#issuecomme...

> it's pretty obvious MS is placing all their chips on WinUI3 Not it isn't, based on the paltry resources and team size they have working on it, the pace of bug fixes (non existent), the fact that in 2024 they stated WPF is on par with WinUI 3 as a recommended GUI framework. I'm not sure what signals to you they are "all in" on it. Look at the size of this thread [0], and how many people tried to give WinUI 3 a chance but have been burned by lack of support. This is not the sentiment that surrounds a platform that has a lot of chips betting on it. [0] https://github.com/microsoft/microsoft-ui-xaml/discussions/9...
In GitHub is no longer independent at Microsoft after CEO resignation
pjmlp·Jul 1, 2024
Supposedly is being worked on for making it more Native AOT friendly. How we got into this mess? WinDev and DevDiv politcs. After the Longhorn debacle, its technologies landed on DevDiv, like WCF and WPF. Sinofsky and friends never were that keen in having .NET coming into their turf, it is no surprise that Hilo sample for Windows 7, then praises COM and C++ for Windows applications[0][1]. Then coming in this path, WinRT came to be, with roots as how .NET was being designed, before Microsoft decided to pivot it as another Java like technology[2]. A bunch of folks in WinDev, weren't happy with C++/CX, so they united to replace it with C++/WinRT, because extensions, when clang and GCC are full of extensions, promised to give back a C++/CX like developer experience in 2017[3], never delivered, went to have fun with Rust/WinRT. Now C++/WinRT

is in maintenance mode[4], and Rust/WinRT never took off, and is now Rust/windows-rs[5]. As paying customer, impacted by those childish attitudes, I would have had the whole team fired. Finally, check the amount of bugs and complaints on their respective repos, https://github.com/microsoft/microsoft-ui-xaml https://github.com/microsoft/WindowsAppSDK https://github.com/microsoft/cppwinrt/ And then compare with Project Reunion vision from 2021, and where we are three years later https://blogs.windows.com/windowsdeveloper/2021/03/29/announ... Mainly because along the way, as if those changes weren't enough, they also decided to reboot their initial approach with Project Reunion, WinAppSDK took another route, and here we are. This is only a short overview of how WinRT went down since Windows 8, thus only those that never advocated for it, can honestly suggest WinUI, as they lack the background of how chaotic it all is.

In Writing GUI apps for Windows is painful
pjmlp·Jun 19, 2024
It suffers from young developes wanting to ship Chrome alongside each application. And it doesn't help that UWP and C++/WinRT turned out such mess that even Microsoft own teams rather use Webviews than native UIs. https://techcommunity.microsoft.com/t5/microsoft-teams-blog/... https://blogs.windows.com/windowsdeveloper/2024/06/03/micros... https://github.com/microsoft/microsoft-ui-xaml/discussions/9...
