#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.

#1,103 – Configuring a Splash Screen

A splash screen is a simple image that appears while your application is loading.  It typically goes away just prior to the appearance of the main application window.

To add a splash screen to your WPF application, you start by adding an image to your project.

Once added to the project, select the image file in Solution Explorer.

Set the Build Action for the file to SplashScreen.

Build and run the application.  As the application starts, the splash screen image will automatically be shown.  It will disappear as soon as the main window of the application appears.
