How do I get the Google/Facebook first name/surname in ASP.NET Identity?

Question

I'm building an application using ASP.NET MVC and Identity and I have Google logins working, but I'd like to display the user's name (from Google/Facebook), so that rather than the website showing as "Hi fred123@gmail.com" it displays as "Hi Fred". I'm aware of how to customise the ApplicationUser, it's just the interaction with the providers I'm not too sure about.

Can anyone help?

On ExternalLoginCallback method you can get all the details.

  //code omitted for clarity
  public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
    {
        var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
        if (loginInfo == null)
        {
            return RedirectToAction("Login");
        }

        var identity = AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);
        var emailClaim = identity.Result.Claims.FirstOrDefault(c => c.Type == ClaimTypes.Email);
        var lastNameClaim = identity.Result.Claims.FirstOrDefault(c => c.Type == ClaimTypes.Surname);
        var givenNameClaim = identity.Result.Claims.FirstOrDefault(c => c.Type == ClaimTypes.GivenName);

        var email = emailClaim.Value;
        var firstName = givenNameClaim.Value;
        var lastname = lastNameClaim.Value;
     }
