App.xaml.cs

This App class is defined as public and derives from the Xamarin.Forms Application class. The constructor has just one responsibility: to set the MainPage property of the Application class to an object of type Page.

using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace AppName
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();

            MainPage = new MainPage();
        }

        protected override void OnStart()
        {
        }

        protected override void OnSleep()
        {
        }

        protected override void OnResume()
        {
        }
    }
}
