The RPX OpenID authentication service is a public API to simplify the integration of single sign on into a public website. This project is a wrapper library written in C# .Net 3.5. It intends to make integration with RPX trivial and rapid.
Included is a sample ASP.Net MVC sample web site to demonstrate the integration points with the library.

If you use this library (or more importantly, you want to but it fails) please send some feedback through to me so that I can upgrade the library. So far I am the only consumer of the library, and it hasn't been that thouroughly tested in the real world. It works for me and I find RPX a great service to interact with, so it would be great if this library could grow to help RPX integration for the .Net community.
