What is the methodology adopted to change the startup page of any particular Silverlight application?

In order to change the startup page of any particular Silverlight application, firstly open the App.xaml.cs file. Subsequently in the Application_Startup handler, set the RootVisual property to the particular Silverlight class. Consider the following example:

In order to find the file name: MainPage.xaml, there must exist a class known as MainPage with MainPage.xaml.cs

private void Application_Startup (object sender, StartupEventArgs)
 
{
 
this.RootVisual = new MainPage();
 
}
