Questions tagged [winui]

WinUI v2.x is a set of technologies from Microsoft that allows UWP developers to add a high-performance set of base controls to their projects. The upcoming WinUI v3 will be replacing the entire UI stack (down to the rendering layer) for all Microsoft desktop development platforms including WPF, UWP, Windows Forms and Win32.

WinUI is the modern native UI platform of Windows. It currently comes in two flavours (2.x & 3.x). Versions 3.x will arrive in March 2021 with Project Reunion 0.5.

While version 2.x adds XAML enhancements and controls to UWP application s, the upcoming Version 3 will be delivering an entirely new UI stack rewrite in high-performance C++ making WinUI available for all types of Windows applications – from Win32 to UWP – for use as the UI layer. More information can be found on the Microsoft site here: Microsoft WinUI
