title: Receiving a SMS message in a .NET application
body: <p>I need to write a .NET application that listens to a SMS message , and then react to it.</p>
  
  <p>I assume i need a SMS gateway to interface between my application and the sender of the SMS.</p>
  
  <p>How could i implement this . Would the listening program need to be a web service or something else ? </p>
  
  <p>Please give me your ideas.</p>
  
  <p>Thanks,
