Answer 1

I wrote an OnBoarding page and then transitioned to Shell. You can't jump into the middle of a bunch of Shell pages, but you can transition from standard navigation to Shell.

In my App.xaml.cs file I did this:

    MainPage = new NavigationPage( new SplashView() );

Then in the code-behind of my SplashView, I did this:

  public partial class SplashView : ContentPage
    {
        public SplashView()
        {
            InitializeComponent();
        }

        protected override async void OnAppearing()
        {
            base.OnAppearing();

            await Task.Delay( 2000 );
            await Application.Current.MainPage.Navigation.PopAsync();
            Application.Current.MainPage = new AppShell();
        }
    }

Hello,​

Welcome to our Microsoft Q&A platform!

Hi, @Saurabh Sharma . For this function, you could detect the login status to specify the MainPage. And set the AppShell as the MainPage instead of using the navigation method after logining in.

   public class App : Application  
   {  
       public static bool IsUserLoggedIn { get; set; }  
       public App()  
       {  
           if (!IsUserLoggedIn)  
           {  
               MainPage = new Login(); //login in and then set the AppShell as MainPage  
           }  
           else  
           {  
               MainPage = new AppShell();  
           }  
       }  
   }
