title: Fetching Access token using Auth token from service in C#
body: <p>I am new to the topic of Oauth and encryption. I need to write a utility where I have authtoken with me and I need to get access token after making a call to the service url say xyzcorp.com. I already have auth token with me I need to use post method to make service call to the url which in turn returns access token. I couldn't find any code snippet which shows how this is done. As I already said I am a newbie into this area, don't have any clue about the implementation in c#. It should be noted that I only have auth token with me.</p>
