If you are using a single image, you must add an image file that is 768×1280 named SplashScreenImage.jpg to your project. The phone automatically scales the image to the correct size. If you want to provide pixel-perfect home screens for all resolutions, you can add the following images to the root folder of your application project.

WVGA 480×800   SplashScreenImage.screen-WVGA.jpg
WXGA 768×1,280 SplashScreenImage.screen-WXGA.jpg
720p 720x1,280 SplashScreenImage.screen-720p.jpg 

  

Each new Windows Phone OS 7.1 project includes a SplashScreenImage.jpg file. To customize the home screen, you can replace your own image with the default image. You can replace the default image with any image you choose, but it must be 480×800 pixels in size, and it should be named SplashScreenImage.jpg . You must set the Build Action property of the image to content.

Example

Here ( Nokia Developer ) there is a example that may be useful to you.

First create a project with Windows Phone Application Template. Create a Windows Phone User Control add a ProgressBar , TextBlock , and Image . The image is the default splash of the project.

<Grid x:Name="LayoutRoot" Background="White" Width="480" Height="800">            
<ProgressBar HorizontalAlignment="Left" Margin="47,692,0,89" Name="progressBar1" Width="383"  />  
<Image Height="512" HorizontalAlignment="Left" Margin="0,0,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="480" Source="SplashScreenImage.jpg" />            
<TextBlock HorizontalAlignment="Left" Margin="185,656,0,114" Name="textBlock1" Text="Please Wait..." Width="111" Foreground="Black" FontSize="22" />        
</Grid>

In the constructor MainPage.xaml.cs we call the function ShowSplash() to load the popup.

private void ShowSplash()
        {
            this.popup = new Popup();
            this.popup.Child = new SplashScreenControl();
            this.popup.IsOpen = true;
            StartLoadingData();
        }

We will initialize the Popup class, and then set the SplashScreenControl class to be hosted in the popup. IsOpen() opens the pop-up .

So far the code will load the pop-up with the progress bar.

Now let's add some process in the background, and when the background process is completed, we will close the pop-up, as a result, the user will see the splash screen. The StartLoadingData() function starts and completes the background job.

private void StartLoadingData()
        {
            backroungWorker = new BackgroundWorker();
            backroungWorker.DoWork += new DoWorkEventHandler(backroungWorker_DoWork);
            backroungWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backroungWorker_RunWorkerCompleted);
            backroungWorker.RunWorkerAsync();
        }

First let's initialize the class BackgroundWorker . We call the function RunWorkerAsync() to start executing a background operation and therefore backroungWorker_DoWork() is called.

void backroungWorker_DoWork(object sender, DoWorkEventArgs e)
        {
            //here we can load data
            Thread.Sleep(9000);
        }

Here we will use the Sleep() function to wait for some time. When backroungWorker_DoWork() expires, backroungWorker_RunWorkerCompleted() is called, which closes the popup.

void backroungWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            this.Dispatcher.BeginInvoke(() =>
            {
                this.popup.IsOpen = false;
            }
            );
        }

So the user can see a screen with the progress bar.
