title: How can I write a REST API to receive an SMS via Twilio Number Using ASp.net Web Api
body: <p>I am new to Web Api/Rest API concept but I plan to use Visual Studio 2012 MVC4 Web Api. 
  How the heck do I create an application to receive a Text/SMS Message via Twilio and send the response back? I have searched several articles here and at Twilio website but none of them give me any insight on how to use MVC4 Web Api. 
  Can somebody please help me and show/give some examples? </p>
