#1,104 – How the Splash Screen Works

You can configure a splash screen in a WPF application by adding an image to the solution and setting its build action to SplashScreen.  The image will appear while the application is loading and then disappear as soon as the main window appears.

You can see how the splash screen works by looking at the code generated at build time for your main application class.  This will be in a file that looks something like App.g.cs.

To open the file, enable the Show All Files option and then look for App.g.cs under the obj directory.

In the Main method, a SplashScreen instance is created and the name of the image is passed to its constructor.  It’s Show method is called and then the normal Application initialization is done. The Show method accepts a boolean indicating that the splash screen should be hidden once the main window is shown.
