Sometimes using DotNetOpenAuth, Service Stack and/or can just get a bit frustrating because they have to handle so many different scenario's - making it complex.
This library tries to simplify that complexity down to two basic steps
1. Redirect to the 3rd party website to log in.
2. Come back to your site and with some user data from the 3rd party website.
What you do with that data, is up to you :)
Did I say 'simple' already?
