title: C# OAuth with service based application
body: <p>I have a service based application which need to connect to an API with OAuth authentification. I had a look to DotNetOpenAuth but things are not clear for me.
  DotNetOpenAuth seems to works with web based application only, right ?</p>
  
  <p>What is the best way to implement OAuth ?</p>
  
  <p>Thanks for your help / advises</p>
