Official Microsoft Learn pages for Windows App SDK, WinUI 3, packaging, deployment, Store, signing, testing, notifications, windowing, title bars, WebView2, and lifecycle.
Context7 Microsoft Learn mirrors for bootstrapper, Store signing/WACK, and WebView2 runtime refresh.
Existing local-docs results only for agent guardrails against stale UWP patterns.

What Was Not Done

No packages were installed.
No authenticated Partner Center dashboards were accessed.
_repos/ was not mutated.
Visual Studio, MSIX packaging, WACK, Appium, and Store submission were not run from this Linux workspace.
Freshness Notes
Windows App SDK downloads page fetched on 2026-07-19 showed stable 2.3.1.
Quickstart fetched on 2026-07-19 referenced Visual Studio 2026 and .NET 10 SDK.
Treat both as recheck-before-use facts, not pinned pack policy.
Trust Notes
github-awesome-copilot and openai-skills are useful for agent behavior and stale pattern detection, but not authoritative for Microsoft platform behavior.
Official Microsoft sample repos should be cloned/indexed later if source-grounded walkthroughs are needed.
