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?

• Dotnetopenid
• RPX
• Other ???

Does anyone know what uses StackOverflow? Is the login user interface configured or provided by an API / service?

Answer 1

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 interface was provided by ID Selector , but since then we have minimized our minimal version.

Answer 2

I will remember the recommendation for DotNetOpenId and add the recommendation for openid-selector (open source version idselector)
