本节我们通过一个简单的发送短信示例来演示一下如果配合使用PhoneNumberChooserTask和SmsComposeTask类。

PhoneNumberChooserTask是选择器，它用于从你的电话簿里选择你要发送短信的电话号码；

SmsComposeTask就是用来启动发送短信组件并显示发送窗口。

注意，这些操作都在用户的操控之中，发送短信一定会显示可视化页面的，而且不会偷偷地在后台发送，因为Windows phone是以用户体验和安全为原则的，后台发送是不允许的，而且发送过程是由用户控制的，你可以选择取消或退出。

SmsComposeTask类的To属性就是目标电话号码，Body就是你要发送的短信的正文。

同样，你会很轻松地就完成这个任务，不信，看看代码吧。
