Case Study: 1 – Scenario 1 (QUESTION 11 – QUESTION 13)
You are developing a Windows Store app by using C# and XAML. The app will allow users to share and rate photos. The app will also provide information to users about photo competitions.
The app stores data by using a class that is derived from the DataStoreBase class.
The app coordinates content between users by making calls to a centralized RESTful web service.
The app has a reminder system that displays toast notifications when a photo competition is almost over. The app gets the competition schedule data from the web service.
The app displays a list of images that are available for viewing in a data-bound list box. The image file list stores paths to the image files. The app downloads new images from the web service on a regular basis.
Relevant portions of the app files are shown. (Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.)
