Earlier this month, at the Microsoft 365 Developer Day event, Microsoft made several important announcements for Windows developers. Among them was an alpha release of WinUI 3.0. This is the second alpha release of the upcoming major update to the WinUI libraries, due to be released toward the end of this year. The centerpiece of this alpha release over the November 2019 alpha release is the addition of the WebView2 control. This is an updated version of the WebView control, based on the new Chromium-based Edge browser. You can read the GitHub issue with the feature proposal for WebView2 here . WinUI 3.0 will be a major update over the 2.x releases. Outside of the WebView2, there will not be many new controls. The team is focused on building out WinUI to be a complete UI framework that can be built on top of either the UWP or Win32 platform layer for new app development. Developers can leverage C++ to build Win32 apps with WinUI or .NET to build WinUI apps with the UWP platform.
