Journey fit
Primary fit
MSIX packaging, code signing, and Store submission are ship-phase tasks that happen after development is complete and the app is ready for distribution. This is a launch task — it takes a built WinUI 3 app and gets it into the hands of users via sideload or Microsoft Store submission.
