MSIX package - Ask the app developer for a new app package. This one isn't signed with a trusted certificate

Anonymous

I am new to MSIX packaging tool. Could you please kindly someone assist me on this?

I have converted my application to MSIX using MSIX packaging tool - https://www.microsoft.com/en-gb/p/msix-packaging-tool/9n5lw3jbcxkf?activetab=pivot:overviewtab & installed the MSIX on windows 10 machine. the installation is not working as expected. Getting an error "Ask the app developer for a new app package. This one isn't signed with a trusted certificate"

I have generated self signed certificate (PFX file) for testing using this link - https://medium.com/the-new-control-plane/generating-self-signed-certificates-on-windows-7812a600c2d8 & attached the PFX in MSIX as well however i am facing the same issue.

I have switched the Update & security option to "Developer mode" but no luck.
