I have signed up with Janrain Engage to incorporate its free widget based openID. But i can't figure out what values to put in the C# code behind. They have provided with a C# helper class, the one below:

this.baseUrl = baseUrl;
}

Forgive me but i'm not a master of C#, but i can't figure out where to put the values for the apiKey and the token_url. Also if a user signs in how to display the username as derived from the accounts he is using to sign up, Google or Yahoo! for example. Also there is no sign out option provided. Any help would be much appreciated as the Janrain developer help is nothing but useless.
