Question 2

Application and Window class relatshionship

Answer 2

Most minimally functional WPF programs contain an instance of the Application class and one or more instances of the Window class.

You can think of a WPF program as a single Application object and one or more Window objects:

• The Application object supports and hosts the Window objects.
• The Window objects comprise the user interface and present the data.

Question 3

Answer 3

Every window on the screen is the visual representation of an instance of the Window class.
