WinUI 3 App Not Showing in Kiosk Mode (Assigned Access) App List on Windows 11 Pro

Hello,

I'm developing a Kiosk application using WinUI 3 on Windows 11, and I'm trying to test it locally using Assigned Access (Kiosk mode).

I’ve packaged the app as an MSIX using Visual Studio and successfully installed it on my machine. The app runs correctly when launched manually from the Start Menu.

However, when I go to Settings > Accounts > Other users > Set up a kiosk, my app does not appear in the list of available apps to assign for kiosk mode.

Here’s what I’ve done:

• Created a WinUI 3 desktop app and added a Windows Application Packaging Project.

Built the app in Release mode, and signed it with a test certificate.

Enabled Developer Mode in Windows 11.

Installed the app via double-click and also using PowerShell with Add-AppxPackage -AllUsers.

Verified the app launches correctly from the Start Menu.

Checked the AppxManifest.xml, and confirmed it includes the following Application entry:

xml
<Applications>
  <Application Id="App" Executable="MyApp.exe" EntryPoint="Windows.FullTrustApplication">
    <uap:VisualElements DisplayName="My Kiosk App" ... />
  </Application>
</Applications>

I suspect the issue may be related to the EntryPoint property. From what I understand, some Kiosk mode configurations expect UWP-style entry points rather than Windows.FullTrustApplication, which is used in WinUI 3 packaged desktop apps.

Questions:

Are WinUI 3 apps (using Windows.FullTrustApplication) supported in Assigned Access on Windows 11?

Is there a specific EntryPoint or packaging requirement for a WinUI 3 app to appear in the Kiosk app list?

Is there a workaround or alternate approach to test a WinUI 3 app in Assigned Access locally?

Any insight or guidance would be greatly appreciated!

Thanks in advance.
