How to get location claim when using Facebook OAuth provider

I'm trying to get the location (or locality) for the user when using facebook OAuth (I haven't tried with google but it's something that I would like too)

I already have set up my scope in my startup file like this:

app.UseFacebookAuthentication(new FacebookOptions
            {
                AutomaticAuthenticate = true,
                AutomaticChallenge = true,
                ClientId = "",
                ClientSecret = "",
                Scope = {"email",
                        "user_friends",
                        "user_location" }
            });

the problem is when I do a 

_signInManager.GetExternalLoginInfoAsync()

I'm always getting the same claim types, so I'd like to add the locality or any other claim type available (like username instead email for example).

when I do:

var user = new ApplicationUser
{
    ProviderKey = info.ProviderKey,
    Email = info.Principal.FindFirstValue(ClaimTypes.Email),
    Name = info.Principal.FindFirstValue(ClaimTypes.GivenName),
    Surname = info.Principal.FindFirstValue(ClaimTypes.Surname),
    AuthenticationType = info.LoginProvider,
    NormalizedUserName = info.Principal.FindFirstValue(ClaimTypes.Email),
    UserName =  info.Principal.FindFirstValue(ClaimTypes.Email),
    Location = info.Principal.FindFirstValue(ClaimTypes.Locality), // I'm getting null here
    Created = DateTime.UtcNow
 };

I think I need to add a configuration for those extra claims I want to collect but I'm not sure where to start, any help will be appreciated.

You need to add location field:

app.UseFacebookAuthentication(new FacebookOptions
{
      AutomaticAuthenticate = true,
      AutomaticChallenge = true,
      ClientId = "",
      ClientSecret = "",
      Scope = {"email", "user_friends", "user_location" },
      Fields = {"location"}
});
