I want to implement a login system by using openid (for login with google, yahoo) for asp.net and asp.net mvc applications, I search over the Internet (and googled that and also stacked :D) but, there is nothing to guide me to implement this; all pages was about libraries (DotNetOpenId, DotNetOpenAuth, etc); can anybody help me to understanding and implementing this? without other libraries? thanks.
http://code.google.com/apis/accounts/docs/OpenID.htmlI am agree with you, and I implemented it by myself. Good luck.
