Topic 1, Scenario 1Background
You are employed as a developer at ABC.com. You are making use of C# and XAML to create a
Windows Store app that enables users to share and rate audio visual media. Data relating to audio
visual media contests will be released to app users.
Application Structure
A derivative of the DataStoreBase class should be used to store app data. A centralized RESTful
web service will be used by the app to synchronize user content. The web service supplies the
app with contest schedule information. The app should be configured to prompt users about the
pending contest completion.
A data-bound list box has been configured to display a list of accessible audio visual media for
viewing. Fresh media is frequently downloaded by the app from the web service.
Business Prerequisites
The app should be able to run on various devices. This includes devices with inadequate
bandwidth. The app should enable users to share and synchronize high resolution audio visual
media, as well as rate media.
Technical Prerequisites
The app should preserve state for every user and device. Every time the app is initiated, the
earlier saved state should be re-established. The app should also preserve user state and media
reworks when swapping between apps. The user interface, tile images, and data should be
reloaded with up to date info from the web service when the app restarts subsequent to being
suspended.
The audio visual media list box should be updated as media is added to the audio visual media file
list. When binding the audio visual media file list to the list box, the audio visual media paths
should be transformed into audio visual media.
Cached audio visual media should only be hosted on the device by the app. the app tile should be
frequently updated with random media from the user’s collection, and be displayed individually.
The tile must display the average user rating as a badge if the audio visual media has a user
rating. If not, the Unavailable glyph should be displayed as a badge. The app tile should allow for
real time updating to make sure that only the latest notification is displayed on the app tile.
Toast notifications indicating the completion of a contest should be based on the contest schedule
obtained from the web service, and be visible for the maximum duration. The toast notifications
should be displayed when the app is running or not. The data of the contest that activated the
toast notification must be displayed when opening this toast notification.
