Windows Application Package Project throws Could not load file or assembly for UWP project.

Is this Nuget Pkg bug or Windows Application Package Project bug - Could not load file or assembly for UWP app added to the package.

When running uwp app by itself, it runs perfect.
But when I add the uwp app to Windows Application Package Project (WAPP) and run WAPP, it throws "Could not load file or assembly.." exception.

I debugged and pinpointed what caused the issue.
When I add NuGet package "System.Linq.Dyamic.Core" or "BingMapsRESTToolkit.Standard", the issue happens.
All works OK before installing the package to TestUWP project. When I uninstall those, they work again.

I created and uploaded the test projects with a solution in one zip file to onedrive: https://1drv.ms/u/s!AqB-HjXxUE9ngeJIpq7KnBsnPqvdSA?e=r2G3vJ

Do I have to give up using those packages?
Or, I have to report the bug to the Nuget package community?
Or, this is a bug caused by MS WAPP project that does not handle those cases?
