taglib-sharp-portable | NET Portable Class Library implementation of TagLib

I'm working on a cross platform application that needs full access to the file system. I'll eventually be targeting both Windows and Mac.

Ultimately, I need to be able to read/write audio file properties (author, genre, etc) for files located anywhere on the system.

I've set the UWP app to have Broad File System Access in the manifest, but this doesn't seem to be enough: access is still denied.

• Using FilePicker is fine for first time access, but the application will need read/write access to files without the user picking them all the time

• The Code Sharing Strategy is .NET Standard instead of Shared Project

• I'm wanting to use TagLib to read/write the file properties (alternatives are welcome)
• My test environment is Windows 10 (so I'm running the UWP app)
• Test files are currently located on the desktop

I remember seeing somewhere that once you open a file with FilePicker you can save the reference/filepath in some app settings so that access will be granted automatically when the app wants to access it without the user. I want to try this, but I can't remember where I read it.

What would be the best approach and/or next steps?

Thanks
