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);

Note:

  • GetCurrentDownloadsAsync

    Returns a collection of pending downloads that are not associated with a group.

  • await Task.WhenAny

    By using Task.WhenAny, you can start multiple tasks at the same time and process them one by one as they’re completed rather than process them in the order in which they#39;re started.

  • From scenario:

/When a customer clicks the details of a listing, the app must start downloading the video tour in the background.

/ When the app starts, the app must verify whether there are any pending downloads, and resume any paused downloads.

/ When downloading the video tours, the app must remain responsive, and each download must be processed on a separate thread.

Incorrect:

  • Not: await Task.WhenAll (need separate threads)

    You apply the Task.WhenAll method to a collection of tasks. The application of WhenAll returns a single task that isn’t complete until every task in the collection is completed. The tasks appear to run in parallel, but no additional threads are created. The tasks can complete in any order.

  • Not: RequestUnconstrainedDownloadsAsync

Used to request an unconstrained download operation

When this method is called the user is provided with a UI prompt that they can use to indicate their consent for an unconstrained operation.

An unconstrained transfer operation will run without the resource restrictions normally associated with background network operations while a device is running on battery.

Topic 4, Fabrikam, Inc Overview

Fabrikam, Inc. is a realtor in the United States.

Fabrikam grants its customers access to a web site, where they can search for houses for rent and for sale. Its customers can enter basic requirements, such as location, number of rooms, dimensions, and a price range. The web site displays a list of houses that meet the customers#39; criteria. The customers can then view more details about each house and can add a listing to a favorites list.

Requirements Business Goals

Fabrikam plans to provide a more interactive experience for its customers. Fabrikam is creating a video tour for each listing. The video tours can be used to visit the property virtually.

Fabrikam plans to create a Windows Store app on Windows 8.1 RT and Windows 8.1 Pro devices.

General Requirements

Fabrikam identifies the following general requirements for the app:

->The app interface must be available in English, Spanish, and French.

->The app must provide the customers with the ability to perform searches the same way that the current web site does.

->It is expected that the customers will view more than 3,000 pictures annually. The main page of the app must show a list of the last 10 pictures that were viewed.

->If pictures are added to a listing that is in a customer#39;s favorites list, the pictures must be downloaded automatically from Windows Azure. This must occur if the app is suspended or not running.

Printing Requirements

Customers must be able to print the details of a listing from the details page by clicking a button within the app.

You plan to add the following XAML markup to the listing details page:

lt;Button x:Name=quot;btnPrint Content=quot;Printquot; Click=quot;InvoJcePrintquot; /gt;.

Video Tour Requirements

Fabrikam identifies the following requirements for the video tours:

->Customers must be able to play the video tour on a different device by using a

button within the app.

->When a customer clicks the details of a listing, the app must start downloading the video tour in the background.

->When the app starts, the app must verify whether there are any pending downloads, and resume any paused downloads.

->The last five viewed video tours that are not on the customer#39;s favorites list must be cached for subsequent viewing.

->Customers must be able to download all of the video tours for the properties that they added to their favorites list.

->The property details page must contain a MediaElement control that will be used to play the video tour of the property.

->When downloading the video tours, the app must remain responsive, and each download must be processed on a separate thread.

  3. Use the ResourceManager class to retrieve localized strings from the code.

  4. Use the x:Uid property for all of the controls that require localization.

  5. Use the x:id property for all of the controls that require localization.

  6. In a subfolder of the app, create three .resw files.

Answer: A,D,F

Explanation: From scenario: The app interface must be available in English, Spanish, and French.

A (not C): You can load string resources from objects such as resource files, libraries, controls, and Windows Store app packages and manifests.

* Example: var res = Windows.ApplicationModel.ResourceLoader(#39;Errors#39;); res.GetString(#39;AlreadyRegistered#39;);

D (not E): x:Uid directive

Provides a unique identifier for markup elements. For Windows Runtime XAML, this unique identifier is used by XAML localization processes and tools, such as using resources from a

.resw resource file.

F (not B): Windows Store apps that use XAML

For Windows Store apps that use XAML, you localize these fields in resources.resw files by using the Resource Editor. To create the United States English version of the manifest fields, you would add an en-us\resources.resw file.

Question No: 39 – (Topic 3)

You need to update the DoWork() method of the background task to meet the requirements.

What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

  1. Get the IsCancellationRequested property from the CancellationToken object and return a TaskCompletionSource object.

  2. Access the Progress object and report the task#39;s progress to the caller.

  3. Update the DoWork() method to receive a Progress object.

  4. Add the CancellationToken object to the client.GetAsync() method.

  5. Confirm that the IsCancellationRequested property of the CancellationToken object is

    true and exit the task.

  6. Update the DoWork() method to receive a CancellationToken object in the arguments of the method.

Answer: D,E,F

Explanation: Cancellation is controlled by the CancellationToken structure. You expose cancellation tokens in the signature of cancelable async methods, enabling them to be shared between the task and caller. In the most common case, cancellation follows this flow:

->(D) The caller creates a CancellationTokenSource object.

->(F) The caller calls a cancelable async API, and passes the CancellationToken from the CancellationTokenSource (CancellationTokenSource.Token).

->The caller requests cancellation using the CancellationTokenSource object (CancellationTokenSource.Cancel()).

->(E)The task acknowledges the cancellation and cancels itself, typically using the CancellationToken.ThrowIfCancellationRequested method.

* From scenario:

/ The SocialPoller background task must run the code in the DoWork() method to collect content from the Contoso feed.

/ The UI must always remain responsive to user actions.

Note:

  • Task-based Asynchronous Pattern

  • CancellationToken Structure

/ Propagates notification that operations should be canceled.

/ CancellationToken. IsCancellationRequested

Gets whether cancellation has been requested for this token.
