How to get email from social network (Identity framework)

Question

What I have: ASP.NET WebAPI application with Identity framework.

What I want: use twitter and facebook for registration and auth.

What is the problem: Identity framework doesn't request for email and other personal information. It returns only username.

Thanks.

Note that twitter does not provide email address via OAuth. Facebook and Google do, but not twitter. — danludwig, Jan 16 '15 at 11:48

In the Startup.Auth.cs file before this code block,

app.UseFacebookAuthentication(facebookAuthenticationOptions);

you should add

facebookAuthenticationOptions.Scope.Add("email");

Then to get the email, check the email claim from the claims cookie after authentication. – danludwig Jan 16 '15 at 11:49

Take note however that even adding that scope, if the targeted user doesn't share his/her email (FB settings) then the framework won't be able to get it – von v. Jan 16 '15 at 11:50

Identity uses OAuth.

Twitter:

The API won't return an email address to you. If you're interested in a user's email address, you'll have to ask the user for it within your own application as a completely distinct act.
