Couldn't get Apple Photos details - C# macOS Sierra 10.12 Xamarin Application

Question

I'm developing an iMac desktop application which is able to upload normal photos as well as Photos library (Previously iPhotos library) to online services like Flickr,SmugMug. Before upgrading to Sierra i was able to get details of iPhotos and could upload too but after upgradation those files/directories doesn't exist.

Below is the block by which i was getting files:

string PhotosLocation = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyPictures), "Photos Library.photoslibrary/Database/apdb/Library.apdb");

But above is not working anymore in Sierra 10.12, if i go to finder itself to locate above mentioned path then i find 'Database' directory but no 'apdb' is there by which i can get Library.apdb

I have googled but no luck, can anybody please show me some pointers on how to get Photos Library files using C#.

Please tell me if i missed any information to share. Thanks.

The Media Library Framework is the place to go if your situation permit.

NSDictionary<NSString, NSObject> options = new NSDictionary<NSString, NSObject>(
    new[] { MLMediaLibrary.MediaLoadSourceTypesKey, MLMediaLibrary.MediaLoadIncludeSourcesKey },
    new[] { new NSString(MLMediaSourceType.Image.ToString()), MLMediaSource.MediaSourcePhotosIdentifier }
);
var ml = new MLMediaLibrary(options);
ml.AddObserver("mediaSources", 0, (obj) => Console.WriteLine("Loaded"));
var src = ml.MediaSources; // returns null first time

In order to access MLMediaLibrary, your application has to be sandboxed and codesigned.
