Answer 1

To access files in your app your should the ms-appx protocol. You might also want to consider using StorageFile too. E.g.

Hello Le Thien Hoang,

If you want to access via URI you need to use the following code:

 Uri uri = new Uri("ms-appx:///Assets/Testing.txt");
            var file =await StorageFile.GetFileFromApplicationUriAsync(uri);

Please notice that in UWP you'd better switch to use StorageFile instead of System.IO.FileStream as suggested by pkr2000. The installed location is some place not like the classic desktop app. It is in a sandbox.

Best regards,

Barry
