Launchers are used to perform tasks provided by the phone operating system. Sending a SMS is a feature of the Windows Phone operating system and can be used by the Launcher API. SmsCompseTask launcher is used to send SMS. This task class is defined as below,



To work with SmsComposeTask, first you need to add a namespace of Microsoft.Phone.Task

Then create an instance of SmsComposeTask.

Next you need to set required or optional parameter for the launcher task. Required parameters for SmsComposeTask are

1. To number
2. Body of SMS

So first set the parameter as below,

And SMS body as below,

Last step, you need to launch the SMS send application provided by operating system. You can show that as below,

If you put all the code together and want to send a SMS on the click event of button then the full code will be as below,

using System;
using System.Windows;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;

namespace test
{
    public partial class MainPage : PhoneApplicationPage
    {
               
        public MainPage()
        {
            InitializeComponent();

        } 

private void btnSendSMS_Click(object sender, RoutedEventArgs e)
        {           

            SmsComposeTask smsComposeTask = new SmsComposeTask();
            smsComposeTask.To = "9158153792";
            smsComposeTask.Body = "hey I am sending u SMS";          
            smsComposeTask.Show();          

        }
