How to access folder & get StorageFile list in WinRT class library?

I am creating a class library. It contains several images. In WinRT app we can enumerate files from specific folder like this.

var folder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("Assets");
var files = await folder.GetFilesAsync(); //which returns List<StorageFile>

While creating class library I can access single image like this

Assembly assembly = typeof(CLASS_NAME).GetTypeInfo().Assembly;
Stream manifestResourceStream = assembly.GetManifestResourceStream("MyImage.png")

The below line returns all the resources of whole assembly, not for particular folder.

string[] names = assembly.GetManifestResourceNames();

I tried this one, but didn't work. It throws exception The specified path (ms-appx:///LibraryName/Images) contains one or more invalid characters.

var sf = await StorageFolder.GetFolderFromPathAsync("ms-appx:///LibraryName/Images");

Now I have nearly 100+ image so in that way it will be donkey work, so how can I access the folder get the list of all the files ?

Please note I am creating class library for Windows Store App.

I just happen to solve this.

GetFolderFromPathAsync only accepts '\' (backslash), not '/' (slash). When I use Application.dataPath from Unity Project, it reports this error too. Now I use 

StorageFolder storageFolder = await
StorageFolder.GetFolderFromPathAsync(
    Windows.ApplicationModel.Package.Current.InstalledLocation.Path + 
    @"\Data\Resources"
);

to get Unity's Resource folder.
