Update your NuGet package in your MVC4 Internet project.

DotNetOpenAuthCore. It will automatically update all dependencies.

Now result.UserName will contain the email adress instead of your name.

    [AllowAnonymous]
    public ActionResult ExternalLoginCallback(string returnUrl)
    {
        AuthenticationResult result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));
        if (!result.IsSuccessful)
        {
            return RedirectToAction("ExternalLoginFailure");
        }

        if (OAuthWebSecurity.Login(result.Provider, result.ProviderUserId, createPersistentCookie: false))
        {
            return RedirectToLocal(returnUrl);
        }

        if (User.Identity.IsAuthenticated)
        {
            // If the current user is logged in add the new account
            OAuthWebSecurity.CreateOrUpdateAccount(result.Provider, result.ProviderUserId, User.Identity.Name);
            return RedirectToLocal(returnUrl);
        }
        else
        {
            // User is new, ask for their desired membership name
            string loginData = OAuthWebSecurity.SerializeProviderUserId(result.Provider, result.ProviderUserId);
            ViewBag.ProviderDisplayName = OAuthWebSecurity.GetOAuthClientData(result.Provider).DisplayName;
            ViewBag.ReturnUrl = returnUrl;
            return View("ExternalLoginConfirmation", new RegisterExternalLoginModel { UserName = result.UserName, ExternalLoginData = loginData });
        }
    }
