Answer 1

Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query

The Windows App Certification Kit (WACK) is a tool that Microsoft provides to validate Windows apps before they are published to the Microsoft Store. If you're getting an error from the WACK when trying to publish your Windows 11 UWP app, it could be for several reasons, including:

Your app violates the Microsoft Store policy, such as content that is offensive, malicious, or violates privacy.

Your app contains compatibility issues with Windows 11, such as incorrect use of APIs, invalid manifest data, or incorrect package structure.

Your app is not optimized for the best performance and user experience, such as poor memory usage, slow startup times, or battery drain.

To resolve this issue, you will need to address the specific error(s) reported by the WACK, and make the necessary changes to your app to meet the requirements of the Microsoft Store. For more information on the Windows App Certification Kit, see the following Microsoft documentation: https://docs.microsoft.com/en-us/windows/uwp/publish/windows-app-certification-kit.
