Skill UI

A comprehensive Command Line Interface (CLI) for managing the entire lifecycle of Windows applications. This skill allows developers to initialize projects, create signed MSIX packages, manage application manifests (AppxManifest.xml), handle development certificates, and access core Windows SDK build tools. It seamlessly supports building applications across various frameworks, including .NET, C++, Electron, Rust, and Tauri, ensuring cross-platform compatibility with native Windows capabilities.

This skill helps developers accurately find and explore the correct Windows API for specific platform capabilities, such as file access, camera usage, notifications, or UI controls. It searches a comprehensive local cache of WinMD metadata, providing full technical details including methods, properties, events, and enumeration values for APIs sourced from the Windows Platform SDK and WinAppSDK. It is indispensable when building complex features requiring deep integration with the Windows operating system.

This comprehensive guide serves as a technical reference for migrating applications from the Universal Windows Platform (UWP) framework to the modern WinUI 3 / Windows App SDK. It details crucial API changes, including namespace updates, window management (CoreWindow to AppWindow), threading models (CoreDispatcher to DispatcherQueue), and best practices for dialogs and background tasks. Essential for developers updating legacy UWP codebases.
