Creating a Windows 8 SkyDrive Metro API -- Issue with LiveDownloadOperationResult

Question

I am using SDK 5.2 - I followed the guide below for downloading files from SkyDrive, but some things have changed in 5.2 for LiveDownloadOperationResult it seems.

guide: http://msdn.microsoft.com/en-us/library/live/hh826531.aspx#downloading_files

here is the code I am using (assume that there is proper authentication/sign-in/access ect)

        public async Task<IStorageFile> DownloadFile(string FileId)
        {
            try
            {
                LiveConnectClient client = new LiveConnectClient(Session);
                LiveDownloadOperationResult result = await client.BackgroundDownloadAsync(FileId);

                return result.File;
            }
            catch (Exception ex)
            {
                throw new SkyDriveAPIException(ex.Message, ex);
            }
        }

I am trying to return a IStorageFile from the result.File property, but no matter what I place in the FileId parameter it will not populate it.  IE: {id}/content or {id}/picture.  The file does download and I get the filestream back, but I cannot get the IStorageFile.

Any ideas?

Thanks,

Steve

               Just for your information, But the code is for windows 8 since it's what I am working on this moment.

               //
                LiveDownloadOperationResult opResult1 = await client.BackgroundDownloadAsync(imageshotlogId + "/content");
                Stream fileStream1 = opResult1.Stream.AsStreamForRead();
                StreamReader streamReader1 = new StreamReader(fileStream1);
                string logText = streamReader1.ReadToEnd();

                //
  Windows.Storage.StorageFolder localFolder = Windows.Storage.ApplicationData.Current.LocalFolder;
                StorageFolder appRootFolder = await localFolder.CreateFolderAsync(gmediabookApp, CreationCollisionOption.OpenIfExists);
                StorageFolder categoryFolder = await appRootFolder.CreateFolderAsync(folderName, CreationCollisionOption.OpenIfExists);
          
                StorageFile imageshotlogStorageFile = await categoryFolder.CreateFileAsync(imageshotlog, CreationCollisionOption.OpenIfExists);
                await FileIO.AppendTextAsync(imageshotlogStorageFile, logText);

You can also do this...

private async Task DownloadFile()
        {
            string skydriveFileId = "file.ea70cpp9e06ae7f3.EA50BB9EEF3!170";

            try
            {
                //create a target file with the correct name and extension
                StorageFile downloadedFile = await ApplicationData.Current.LocalFolder.CreateFileAsync("FileFromSkyDrive.txt");

                //pass in the file id (path) and the StorageFile you created and it's filled with the downloaded files data
                await client.BackgroundDownloadAsync(skydriveFileId + "/content", downloadedFile);
            }
            catch (Exception e)
            {
                infoTextBlock.Text = "Error downloading file: " + exception.Message;
            }
        }

This is also Windows 8 code.
