Step 1 :

 Add the following plugin in your projects :

PERMISSIONS :

    1- android :  <uses-permission android:name="android.permission.READ_CONTACTS" />

2- IOS :

	<key>NSContactsUsageDescription</key>

Page code :

using System;
	using System.Collections.Generic;
	using System.Linq;
	using System.Text;
	using System.Threading.Tasks;
	using Xamarin.Forms;
	namespace Sample.ContactService
	{
	public partial class MainPage : ContentPage
	{
	#pragma warning disable CS4014 // Because this call is not awaited, execution of the current method continues before the call is completed
	public MainPage()
	{
	InitializeComponent();
	GetContacs();
	}
	#pragma warning restore CS4014 // Because this call is not awaited, execution of the current method continues before the call is completed
	async Task GetContacs()
	{
	var contacts = await Plugin.ContactService.CrossContactService.Current.GetContactListAsync();
	lstContacts.BindingContext = contacts;
	}
	}
	} C# Code : <?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:Sample.ContactService" x:Class="Sample.ContactService.MainPage"> <StackLayout> <ListView x:Name="lstContacts" ItemsSource="{Binding .}"> <ListView.ItemTemplate> <DataTemplate> <ViewCell> <StackLayout> <Label Text="{Binding Name}"/> <Label Text="{Binding Email}"/> <Label Text="{Binding Number}"/> </StackLayout> </ViewCell> </DataTemplate> </ListView.ItemTemplate> </ListView> </StackLayout> </ContentPage>
