How to destributed unsigned or self-signed MSIX using Windows Package Manager/winget

Question

I have a UWP application packaged as an MSIX.

I want to distribute it via Windows Package Manager/winget-cli

As I understand it, MSIX has to be signed to be installed.

If I sign it with a self-signed certificate it is rejected, because that certificate is not installed on the target machine.

Do I have to purchase a Code Signing certificate?

Is there no other option?

Hello,

Welcome to Microsoft Q&A!

Windows Package Manager usage is out of the scope of the tag. But just talk about the sideload feature of UWP apps, it is required to have your app be signed by a certificate that is trusted in local machine. There is no other way if you want to sideload the app. It depends on you which certificate you want to use but the certificate must be trusted and installed on the local machine.

Thank you.
