-In this example, the code-behind implements a class that derives from the [`Window`](http://avaloniaui.net/docs/quickstart/window) class. The `x:Class` attribute is used to associate the markup with the code-behind class. `InitializeComponent` is called from the code-behind class's constructor to merge the UI that is defined in markup with the code-behind class. The combination of `x:Class` and `InitializeComponent` ensure that your implementation is correctly initialized whenever it is created. The code-behind class also implements an event handler for the button's `Click` event. When the button is clicked, the event handler changes the text of the button by setting a property on the `Button` control.
