Microsoft Essentials of Developing Windows Store Apps using C# Sample Questions:

1. You need to correctly display notifications on the app tile.
Which code segments should you insert at line AX24? (Each correct answer presents part of the solution. Choose all that apply.)

A) Option D
B) Option A
C) Option C
D) Option B

2. DRAG DROP
You are developing a Windows Store app.
The following code segment defines an event procedure. (Line numbers are included for reference only.)

You need to define a custom help setting in the event procedure.
Which three code segments should you insert in sequence at line 03? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)

3. You are developing a Windows Store app. An XML document named tileXmlDocument contains the layout of the app tile.
You need to configure a tile notification that will display for 15 seconds.
Which code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose all that apply.)

A) Option D
B) Option A
C) Option C
D) Option B

4. DRAG DROP
You are developing a Windows Store app that will make calls to a web service.
The app must read and write the web service URI to and from configuration settings. The
configuration settings must follow the user so that when the app makes calls to the web
service, it calls the same URI, regardless of which device the user is using.
You need to retrieve and store the web service URI.
You have the following code:

Which code snippets should you insert in Target 1 and Target 2 to complete the code? (To answer, drag the appropriate code snippets to the correct targets in the answer area. Each code snippet may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

5. You are developing a Windows Store app that will read data from a file that is stored on a hard disk. The app will display that data on the screen.
You need to ensure that portions of the app can be reused in WinRT, Windows Presentation Foundation (WPF), Microsoft Silverlight, and Windows Phone apps.
What should you do?

A) Create a page and a ViewModel object. Set the page's DataContext property to reference the ViewModel object. Program the page so that its Loaded event reads data from the file and populates the properties of the ViewModel object with that data. Program the page to consume the data by using data binding.
B) Create a page and a ViewModel object. Set the page's DataContext property to reference the ViewModel object. Program the ViewModel object to load data from the file and populate its properties with that data. Program the page to consume the data by using data binding.
C) Create a page, a ViewModel object, and a FileHelper class. Set the page's DataContext property to reference the ViewModel object. Program the ViewModel object to use the FileHelper class to load data from the file, and populate its properties with that data. Program the page to consume the data by using data binding.
D) Create a page and a ViewModel object. Program the page to use the Loaded event to load data from the file and then update the page contents to reflect the data from the file. Program the ViewModel object to use the Windows.Data.FileLoader class to populate its properties from the file.
