Best OpenId API for ASP.NET MVC application

Question

I am developing an ASP.NET MVC application and I want to use OpenId.

What is the best option?

Does anyone know what StackOverflow uses? Is the Login UI custom-developed, or provided by an API/service?

This question is a bit old now, relative to the pace of innovation in this area. SO doesn't favour duplicate questions, otherwise I'd re-ask this one, looking for a contemporary set of answers. — Drew Noakes, Aug 02 '10 at 13:38

We use the excellent DotNetOpenId library here on Stack Overflow:

http://code.google.com/p/dotnetopenid/

now moved to:

http://www.dotnetopenauth.net/

Our original login UI was provided by ID Selector, but we've since rolled our own minimalist version.

Well, looks like we need to upgrade our ID Selector to RPX! – Jarrod Dixon Feb 09 '09 at 01:45
Yes looks like it. Let us know how it goes. – Jedi Master Spooky Feb 09 '09 at 01:47

-1 on RPXNow. http://blog.nerdbank.net/2009/01/why-using-rpxnow-is-bad-idea.html – Andrew Arnott Feb 17 '09 at 04:23
I'm actually about to migrate from RPX back to openid-selector. The RPX servers are down about 5% of the time that someone tries to register. – Portman Sep 10 '09 at 17:45

Would you modify your answer, nearly a year on? Does this information still hold true today? – Drew Noakes Aug 02 '10 at 13:36

I'll second the recommendation for DotNetOpenId and add a recommendation for openid-selector (open source version of idselector)

Thanks! Just tried it, Exellent compaird to the idselector.com's. Specially if you do need to change the look or language :P – Nikita Ignatov Feb 22 '09 at 11:24
Because it was the first. I believe there are better alternatives now, but I don't know what they are. I use RPXnow whenever possible. – John Sheehan Jun 02 '10 at 05:08
