browsing in this website, i found some interesting suggestions. SocialAuth.net and DotNetOpenAuth.
i started using SocialAuth. It’s very simple to use and it worked (i only tried with google so far thou). My only problem with this library is that it doesn’t provide a way to retrieve the Contacts from the providers it offers without logging you in with the new (or latest) provider you requested the list of Contacts.
in other words, i MUST sing in my people with a local username and password for security reasons. BUT i would like to benefit from this library’s feature of getting contacts from different providers. Thing is that it overrides my currently logged in user (using FormsAuthentication) for the Authentication Token sent by google.
Has anybody confronted this issue?
Does DotNetOpenAuth doesn’t have this flaw?
Thanks
Maybe you should check the last changes in source:

As you can see, in r320 it seems they have fixed this issue
