title: How to set proxy settings for my application in .NET
body: <p>I have an application in C# which uses a service reference to send SMS through a web service. The user's internet connection needs to pass through a proxy server in order to reach the world.</p>
  
  <p>So my question is how to tell .NET to call web service through the proxy? Or how to set proxy settings for internet connection of my application just like what you can do in YMahoo Messenger?</p>
