Warning

To install the generated MSIX/APPX package:

(1) Enable the Developer Mode or Sideloading apps on the target system;

(2) Ensure that the certificate, used for signing, is trusted on that system. If you are using the self-signed certificate, install it manually to the Trusted People or Trusted Publishers local machine certificate store. By adding a certificate to local machine certificate stores, you affect the certificate trust of all users on the computer. It is recommended that you remove those certificates when they are no longer necessary to prevent them from being used to compromise system trust.
