Are you adding WinAppSDK to a UWP app? Or is the UWP part of the title incorrect?

Are you adding WinAppSDK to a UWP app? Or is the UWP part of the title incorrect?

Sorry, I have mentioned the wrong one in title. I am using the latest WinAppSDK package in my WinUI application and uploading the package in Windows Store. But it throws the error as mentioned above.

Thank you for the update on the app type, and title. Are you able to also provide us with:

• a repro for this error.

Exact same error !
Just updated .NET SDK to 8.0.10, Visual Studio and packages in my WinUI app: WinAppSDK from 1.5.240404000 to latest (1.6.240923002)

I wasn't sure it came from WinAppSDK or VS or .NET or another updated package (as SDK.BuildTools), but you seems to confirm that it come from WinAppSDK. After downgrading to 1.5.24 again (only downgrading WinAppSDK), the Store display another error:

"Package acceptance validation error: The package InstantSub.Packager_2024.1107.2221.0_x86.msix uses an unsupported version of file makepri.exe (10.0.26100.1742)."

Could .NET 8.0.10 update be the problem here ?
My app is targeting OS version 10.0.22621 (not 10.0.26100).

Thanks.

Ok, I got it.

Problem was the "Microsoft.Windows.SDK.BuildTools" nuget package version 10.0.26100.1742.
Downgrading to 10.0.22621.3233 has fixed validation problem on the Microsoft Store.

This issue has been addressed in the latest WebView2 SDK, available here: https://www.nuget.org/packages/Microsoft.Web.WebView2/1.0.2903.40

To work around this issue, add an explicit reference to the WebView2 package. A future Windows App SDK release will include this reference.
