Let’s look closer some items.

ContentPage : MainPage is inherited from the ContentPage class which in turn is a class that represents a single view.

InitializeComponent(); : An XAML compiler method, that produces named item. Constructor to intialize all the controls which are present in MainPage.xaml page. Links the XAML components with their peers in XAML code-behind.

OnCounterClicked : Copes with Clicked event of the button with the name CounterBtn.

• object sender: Which panel calibrated this control; where this event originated from.
• EventArgs e: Contains event data.

SemanticScreenReader.Announce(CounterBtn.Text); : Speaks aloud the new button text through the device’s screen reader.
