The Window class provides you with a bunch of properties, methods, and events to customize the look of the window, and perform specific operations or to be notified of the current context. To ask the client area to support transparency, set the AllowsTransparency property of the window to true. This is often useful when you want to create a custom-shaped window or a skinned theme.
You can change the default icon of the window by setting the Icon property and enable/disable the window resizing by setting the ResizeMode property. You can also set the window title, startup location, window state, window style, and taskbar visibility by settings the Title, WindowStartupLocation, WindowState, WindowStyle, and ShowInTaskbar properties, respectively.
Not only these but you can bring the window to the foreground by calling its Activate() method and close the window by calling the Close() method available in the Window class. Sometimes, when you want to hide the window instead of quitting it completely, you can utilize the Hide() method to make the window hidden and bring it back again by calling the Show() method on the same instance.
The class also exposes some events to notify you of the current contextual information. You can use the Activated, Deactivated, Closing, Closed, and StateChanged, events in your code to get such notifications.
