How do I implement OpenID in my web application?

Question

Does Stackoverflow create a new OpenID when a user registers with an email address (i.e. does not provide an existing OpenID)? How do you do that? Do you have code examples in C#? Java? Python?

Answer 1

You can find OpenID implementations here. If you just want more information, I would check out the OpenID site.

Answer 2

I think you are mis-understanding OpenID, the process of registering and OpenID is the responsibility of the user, you'll note that there is no place to signup here without an OpenID.

Answer 3

The Plaxo OpenID recipe (from the OpenID site) was one of the better howtos I've seen.

Answer 4

Scott Hanselman posted a while back about setting up OpenID in .net.
