MSIX framework uninstall reports success without removing package when matched by PackageFamilyName

winget uninstall

Brief description of your issue

I was trying to use winget to install the 2.0.1 Windows App SDK package for a test automation scenario (its manifest has a small bug in its package name which prevents the uninstall command from locating the package- I'm working on separately trying to fix that). Anyway, when testing uninstall with the private version of the manifest, winget reports success, but the packages are still installed.

WinGet’s non-elevated seems to use FindPackagesByPackageFamily(..., PACKAGE_FILTER_HEAD, ...), which does not resolve this framework package. Also, elevated lookup can encounter multiple packages under the shared package family. The installer deploys several MSIX identities (framework, Main, Singleton, and DDLM), while the WinGet manifest exposes only one PackageFamilyName.

Returning success after finding nothing to remove is independently a bug, even if framework uninstall is unsupported, IMO.

Steps to reproduce

winget uninstall --manifest C:\data\test\wasdk-2.0.1-corrected --version 2.0.1 --disable-interactivity --silent --verbose-logs

where the corrected manifest has this edit:

diff --git a/manifests/m/Microsoft/WindowsAppRuntime/2/0/2.0.1/Microsoft.WindowsAppRuntime.2.0.installer.yaml b/manifests/m/Microsoft/WindowsAppRuntime/2/0/2.0.1/Microsoft.WindowsAppRuntime.2.0.installer.yaml

Expected behavior

WinGet removes WASDK 2.0.1, or returns a clear unsupported or ambiguous-package error.

Actual behavior

Exit code is 0 , but the package remains installed:

The verbose log contains:
