Description

When checking the Windows App Certification Toolkit (see the last line), we noticed that splash screen was randomly missing from one of the package versions going to Microsoft Store (which means the app would not start):

This has been randomly happening when building with Visual Studio, but this package was build with dotnet build (in release configuration). The build process did not report any problems.

This may be related to the problem of multiple build processes starting, see #23495 .

Steps to Reproduce

Build a Windows package for GnollHackM. Maybe every other time the splash screen icon is missing from the package when build with Visual Studio, and pretty randomly when built with dotnet build. This may be fixed by closing Visual Studio before building with dotnet build, but I haven't tested this enough yet due to the random nature of the omission.

Version with bug

9.0.0-preview.6.24327.7

Is this a regression from previous behavior?

Not sure, did not test other versions

Last version that worked well

Unknown/Other

Affected platforms

Windows

Affected platform versions

Windows 11

Did you find any workaround?

Closing Visual Studio first, and then building with dotnet build may potentially help here, too, see #23495 . Also, we added an AfterTargets target to the build process that copies the backup splash screen icons from Assets directory to the right place in the obj directory to make sure they indeed are there.
