  4. Create an HttpClient object and use the PutAsync() method to perform the transfer the video file asynchronously.

  5. Create a BackgroundTransfer object and call the UploadAsync() method to transfer the video file.

  6. Use the XHR class to initiate and run a web upload of a video file.

Answer: C,F

Explanation: C: To ensure your Windows Store app is network ready, you must set the capability in the project Package.appxmanifest file.

Capability: Internet (Client amp; Server)

Gives the app inbound and outbound network access from the Internet and networks in public places like airports and coffee shops.

This is the internetClientServer capability in the app manifest. A:

  • BackgroundUploader class

    Background Transfer is primarily designed for long-term transfer operations for resources like video, music, and large images. For short-term operations involving transfers of smaller resources (i.e. a couple KB), use the Windows.Web.Http namespace (not D).

  • BackgroundUploader.CreateUploadAsync | createUploadAsync methods Initializes an asynchronous UploadOperation.

  • Example:

BackgroundUploader uploader = new BackgroundUploader(); uploader.SetRequestHeader(quot;Filenamequot;, file.Name); UploadOperation upload = uploader.CreateUpload(uri, file);

// Attach progress and completion handlers. await HandleUploadAsync(upload, true);
