Access is denied error windows phone 8

Question

I am getting error on following line

Answer 1

http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.knownfolders.pictureslibrary says Windows Phone 8: This API is not intended to be used directly from your code.

In my app I used

             var photoChooserTask = new PhotoChooserTask();
             photoChooserTask.Completed += OnPhotoChooserTask_Completed;
             photoChooserTask.Show();

to pick a photo.

Answer 2

I was having same problem but my issue was that i was reading too much files using iBuffer so it was taking too much memory and it was causing out of memory issue. So i optimized it and this issue was fixed.
