DLLs missing when running MSIX packaged Application after updating from .NET Framework 4.8 to .NET 6

[Valdimar_Thor]

Hi, I've been using MSIX now for a few years without any real issues for my WPF .NET Framework 4.8 application, but after updating it to .NET 6 I'm getting errors with missing dlls. 

to create the msix package I'm running the command as follows:
C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x64\makeappx.exe" pack /d C:\Builds\MyApp\Versions\1.0.0.1\ /p C:\Releases\MyApp\Versions\MyApp-1.0.0.1.msix /v /o

I've added the windows packaging project to my solution and reference the WPF project but with same results. 

Is there something I'm missing here...well there must be but I have no idea what it is.

Regards Valdimar Thor

Consider this closed.

I'm using the PRISM library and it's config catalog to load the dlls and that seems to be the problem. As soon as I changed it to the default module catalog, everything worked as intended.
