Hello World Application: Xamarin.Forms

What is Xamarin Forms :

Xamarin.Forms is a new library that enables you to build native UIs for iOS, Android and Windows Phone from a single, shared C# codebase. It provides more than 40 cross-platform controls and layouts which are mapped to native controls at runtime, which means that your user interfaces are fully native

Step 1:

Create a new solution.

Click on the "New Solution"

Step 2: Select Forms App and click Next

Step 3: Add App name and click Next

This is how the project stricture will look like when the solution is created:

App.xaml:

<?xml version="1.0" encoding="utf-8"?>
<Application xmlns="http://xamarin.com/schemas/2014/forms" 
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="HelloXamarinForms.App">
    <Application.Resources>
        <!-- Application resource dictionary -->
    </Application.Resources>
</Application>

App.xaml.cs:

using Xamarin.Forms;

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

            MainPage = new HelloXamarinFormsPage();
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }
    }
}

<?xml version="1.0" encoding="utf-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:local="clr-namespace:HelloXamarinForms"
    x:Class="HelloXamarinForms.HelloXamarinFormsPage">

    <Label Text="Welcome to Xamarin Forms!" VerticalOptions="Center"
        HorizontalOptions="Center" />
</ContentPage>

{
    public partial class HelloXamarinFormsPage : ContentPage
    {
        public HelloXamarinFormsPage()
        {
