winapp-cli

CLI for Windows app packaging, MSIX creation, certificates, and Microsoft Store deployment across frameworks. The Windows App Development CLI ( winapp ) is a command-line interface for managing Windows SDKs, MSIX packaging, generating app identity, manifests, certificates, and using build tools with any app framework. It bridges the gap between cross-platform development and Windows-native capabilities. Use this skill when you need to: Initialize a directory with required assets (manifest, certificates, libraries) for building a modern Windows app. Supports SDK installation modes: stable , preview , experimental , or none . Create MSIX packages from prepared directories with optional signing, certificate generation, and self-contained deployment bundling. Add temporary package identity to executables for debugging Windows APIs that require identity (notifications, Windows AI, shell integration) without full packaging. Generate AppxManifest.xml files and update image assets from source images, automatically creating all required sizes and aspect ratios.
