B. Loaded
C. Tapped
D. ManipulationStarted

Not B: Loaded occurs when a FrameworkElement has been constructed and added to the object tree, and is ready for interaction. Not C: Tapped occurs when an otherwise unhandled Tap interaction occurs over the hit test area of this element.
Not D: ManipulationStarted represents that the manipulation recognition logic has detected pointer movement.
Q15. You are developing a Universal Windows Platform (UWP) app. The application architecture uses the Model-View-ViewModel (MVVM) pattern.
You are designing a form to add new contacts to the app. The form contains an input field named LastName and a Save button. You need to ensure that when LastName is empty, the Save button is disabled.
What should you use?
A. On the Save button, change the IsDefaulted property and the IsDefault property.
B. Use an InputType enumeration that has a Command member.
C. Use a CommandBinding object that contains a CanExecute event.
D. On the Save button, change the IsSealed value.

Q16. You are developing a Universal Windows Platform (UWP) app that will be published to the Microsoft Store.
The app will contain the following method.
JavaScript in the app will call the method. You need to implement the method. What should you do first?

B. Add a class file to the project.
C. Create a portable class project.
D. Add the method to the App.xaml.cs file.
Correct
Answer: A
Explanation:
By using the Windows Runtime, you can create components (essentially DLLs) in C++, C#, or Visual Basic, and call into them in a simple and natural way from a Windows Store app that's built by using JavaScript.
