What OpenID solution is really used by Stack Overflow?

I know there are other questions about this, but they are outdated, and I cannot find the answer that would be reliable anywhere.

What is really used by Stack Overflow to autentificate users? The site DotNetOpenAuth claims it is. But to me the most (visually) similar looks to be OAuth C# Library.

So what does it really use? Or how can I mimic the same UI?

I want to create the very same OpenID authentication using ASP.NET MVC.

Solution

  • StackOverflow uses DotNetOpenAuth.

    but fortunately we have an excellent dialog with Andrew Arnott, the primary author of the open source DotNetOpenAuth library we use
