Modify startup screen for Windows Phone

Applications usually need to pre-load some resources to ensure that these resources are available immediately after the application can be started, even if this causes the application to not be displayed until the load is complete. The startup screen is a content area that is displayed when other content is being loaded.

All Windows Phone project templates contain a boot screen image. Its initial file name is splashscreenimage.jpg, which is automatically displayed when the program is being started. If it takes more than one second for your program to display the first page, we recommend that you set a startup screen for the program.

You can use the default boot screen provided by the Windows Phone Project template, or create your own boot screen to display the trademark or product information, such as the application logo and disclaimer. If you want to display important information on the startup screen and extend the display time, you can rewrite the onnavigatedto () method on the page and call M: system. threading. thread. sleep (system. int32) specifies the time when you want to start the screen display.

To create a custom startup screen, first create a 480 * jpg image named splashscreenimage.jpg and replace the default image of the same name in the application project. (set the buildaction attribute to content ). In this way, the custom image will be displayed when the program starts.

Another option is to use screenshots on the application homepage as the startup screen to create a Fast startup effect. If you want to use the homepage screenshot of the application as the startup screen, try the following operations to capture a screenshot:
Hide all data that will change when the program runs
Verify that the simulator zoom rate is set to 100%
Screenshot of the simulator screen range
Make sure the image size is 480 * and saved as splashscreenimage.jpg.
