Microsoft has released a quick-start guide for developers to create native WinUI 3 applications for Windows 11 in about 30 minutes, using tools like VS Code, .NET 10, GitHub Copilot's free tier, and Microsoft's winapp CLI, without requiring Visual Studio. The guide details project scaffolding, AI integration for features, testing, and packaging as an MSIX installer. The AI agent, winui-dev, is a specialized plugin for WinUI tasks, and developers are encouraged to connect it to the Learn MCP server for updated documentation. This initiative aims to move developers away from web wrappers and Electron-style applications, which use more RAM. Microsoft announced at the Build 2026 conference that "3" will be removed from WinUI's name, reinforcing its long-term stability. WinUI 3 is being integrated into Windows 11 components, although some apps still use WebView2 technology, which consumes more RAM than native options.
