AppXInstaller issue: Package with empty Package Extensions node in manifest


Consider a package with a manifest including:








This package creates OK using makemsix, but will fail to install using the AppInstaller on 20h2 (did not try other versions, but presumably the same).


Removing the <Extensions/> line solves this issue.  As with other cases that I have documented, AppInstaller should not reject legal packages.

Hi @TIMOTHY MANGAN, Can you file a Feedback for this via the Feedback hub? Can you tell us what is the failure message you get with App Installer?
