        var authClient = new LiveAuthClient();
        var authResult = await authClient.LoginAsync(new string[]  "wl.skydrive", "wl.skydrive_update" );
        if (authResult.Session != null)
        
            var liveConnectClient = new LiveConnectClient(authResult.Session);

            // Upload to OneDrive.
            LiveUploadOperation uploadOperation = await liveConnectClient.CreateBackgroundUploadAsync(
                uploadPath, fileName, uploadInputStream, OverwriteOption.Rename);
            LiveOperationResult uploadResult = await uploadOperation.StartAsync();
            HandleUploadResult(uploadResult);
        
    
    catch (LiveAuthException ex)
    
        // Handle errors.
    
    catch(LiveConnectException ex)
    
        // Handle errors.
    





var pendingOperations = await LiveConnectClient.GetCurrentBackgroundUploadsAsync();
foreach(LiveDownloadOperation pendingOperation in pendingOperations)

    try
    
        var opResult = await pendingOperation.AttachAsync();
        // Handle results.
    
    catch
    
        // Handle errors.
