title: Asp.NET Web API Displaying all controller's routes
body: <p>Is there a way to display all the available services that the application exposes via Web Api actions? For example when a user goes to <a href="http://someurl/api/" rel="noreferrer">http://someurl/api/</a> he will get a list of all the available services, their descriptions and the required parameters? I remember that I've seen this once but I cannot find any documentation for it/ </p>
