ASP.NET Core Social Login RC1

Question

I was using ASP.NET MVC 5 and all was working fine, now I'm working with ASP.NET Core and the social login with Facebook is not getting the email. I have tested with my account and others as well. I'm using:

"Microsoft.AspNet.Authentication.Facebook": "1.0.0-rc1-final"

This is the code in the Account Controller:

// REVIEW: handle case where email not in claims?
var email = loginInfo.ExternalPrincipal.FindFirstValue(ClaimTypes.Email);

Startup.cs Example:

app.UseFacebookAuthentication(options =>
            {
                options.AppId = "**********";
                options.AppSecret = "********";

            });

Any ideas how to fix it?

The issue seems to be specific to FaceBook and is documented fairly well in github here and here. Things to ensure you have setup correctly:

Ensure app status is "live" https://developers.facebook.com/apps/myappid/review-status/
When invoking app.UseFacebookAuthentication ensure you add "email" to the scope like so
If you're still unable, try setting fields explicitly like the example below:

Options.UserInformationEndpoint = 
   "https://graph.facebook.com/me?fields=email,timezone,picture";

If you're still not getting what you need, upgrade to RC2.
