I am getting error on following line
StorageFolder picturesFolder = KnownFolders.PicturesLibrary;
Exception is: ex {System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) at Windows.Storage.KnownFolders.get_PicturesLibrary() at WinTooth.MainPage.d__0.MoveNext()} System.SystemException {System.UnauthorizedAccessException}
I have also added lines to register for a file association extension. Please suggest/help.
