How to access content from a Net Standard 2.0 class libary from UWP

Question

We have a UWP app which references a UWP class library. The UWP class library has a Common folder with files that are required at runtime.

The files are marked Copy As Content. The files are copied to ..\UWP\bin\x64\Debug\Appx\<LibraryName>\Common. The app finds those files at runtime in package.InstalledLocation\<LibraryName>\Common

The UWP class library is now a .NET Standard 2.0 class library. At runtime the Common folder is now copied to a folder at the same level as the Appx folder ..\UWP\bin\x64\Debug\Common where I cannot access. I tried

StorageFolder installedFolder = package.InstalledLocation;
StorageFolder parentFolder = await installedFolder.GetParentAsync();

but parentFolder returns null. How do I access files and folders that are content from a .NET Standard 2.0 class library?

You can not get the file in the .Net standard class library from the InstalledLocation. To access the files, you can mark the file as Embedded Resource and Copy Always, then expose a method to access the file stream.
