问题
I've heard different things. Seems like Microsoft experimented with a beta service, but I don't know if it's still available, or ever made it into production.
If Windows Live ID is an OpenID Provider, where is the endpoint?
回答1:
No. Windows Live ID is not an OpenID Provider. They use a proprietary protocol. Ever since the close of their "beta" period, they've never announced plans to continue with it.
回答2:
Check out this, I believe they use OAuth (not OpenID).
回答3:
Looks like it really hasn't made it into production.
