You need to implement the photo viewer control to meet the requirements.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

A.
Add the themes\generic.xaml file to the project and reference it from the control.

B.
in the constructor of the class, set the value of the DefauItStyleKey to the type of the control.

C.
Create a custom control.

D.
Create a composite control.

E.
Create a user control.

Explanation:

The SemanticZoom control enables the user to switch between two different views of the same
content. One of these is the main view of the content. The second view is a view of the same content
represented in a way that allows users to quickly navigate through it. For example, when viewing an
address book, the user could zoom in on a letter and see the names associated with that letter.
To provide this zooming functionality, the SemanticZoom control uses two other controls: one to
provide the zoomed-in view and one to provide the zoomed-out view.
* From scenario:
The app must include a photo viewer. When photos are added or deleted in the photo viewer
window, they must animate in and out of the field of view. Remaining photos must move to fill the
empty space created when photos are deleted. The photo viewer must support semantic zoom.

Scenario Geese
Background
You are developing a Windows Store app. The app will allow ornithologists to photograph
migrating geese, taking note of the location, heading, and weather conditions at the time each
photo is taken.
BusinessRequirements
The app must adhere to the following requirements:
• Create and store photographs of migrating geese.
• Record the location and weather conditions where the photograph was taken.
• Record the heading and time that the photograph was taken.
• Allow the user to display the information on any device that supports the
PlayTo feature.
TechnicalRequirements
General:
The app must meet the following technical requirements:
• The app must store images and image metadata in the Pictures Library.

• The metadata logic must be encapsulated within a reusable component named
LogicComponent1.
• The metadata logic must be available to Windows Store apps written in Visual
Basic, C#, JavaScript, and C++.
Hardware:
• The app requires a device with camera, compass, and GPS features.
• The app requires a device with Internet capabilities.
