What problem does it solve? Preparing a WinUI 3 application for release involves certificate generation, code signing, MSIX packaging, and Microsoft Store submission, each with error-prone steps like publisher mismatches and untrusted certificates. This Skill provides the exact commands and workflows to handle the entire release pipeline correctly. ## Core Features & Use Cases - MSIX Packaging & Signing: Generate dev certificates, trust them, and package signed MSIX installers using the winapp CLI, including self-contained deployment and timestamped production signatures. - CI/CD Automation: Set up GitHub Actions pipelines that build, package, and upload MSIX artifacts on every push. - Microsoft Store Submission: Follow the release-driven msstore CLI pipeline for automated Store publishing, with Partner Center requirements like age ratings, screenshots, and privacy policies. - Use Case: You finished a WinUI 3 app and need to ship it. Use this Skill to generate a certificate, sign a self-contained MSIX, and wire up a GitHub Actions workflow that publishes to the Microsoft Store on each release. ## Quick Start Ask the assistant to package and sign your WinUI 3 Release build output into an MSIX installer using a generated development certificate.
