- Sigstore for code signing?

At first glance, it seems like this would cost a decent amount of money 😬.

Start by reviewing the linked Microsoft Store Publish GitHub Action, the Windows code-signing guide, and the Azure Code Signing example. Compare those options with Sigstore and determine the cost and publishing requirements. Done means the application is signed and published to the Microsoft Store, if a viable approach is selected.
