Log user information after successful login

Question

In Identity core, I am trying to log the user information after successful login but I am just getting empty UserName in the LogSignIn action.

In this method I am calling LogSignIn action by sending HttpContextBase type object and notify enum to get the success or error message.

Action Login

public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
    if (!ModelState.IsValid)
    {
       return View(model);
    }
    var result = await SignInManager.PasswordSignInAsync(model.Username, model.Password, model.RememberMe, shouldLockout: false);
    switch (result)
    {
        case SignInStatus.Success:
            {
                SignInLogger.LogSignIn(HttpContext, Notify.Success);
                return RedirectToLocal(returnUrl);
            }
        case SignInStatus.LockedOut:
            return View("Lockout");
        case SignInStatus.RequiresVerification:
            return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
        case SignInStatus.Failure:
        default:
                SignInLogger.LogSignIn(HttpContext, Notify.Error);
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
      }
}

In this method I am trying to log the user information to the DB but Idenity don't have the value in the Name. SignIn Logger

public static void LogSignIn(HttpContextBase httpcontext, Notify notifymessage)
{
    using (var context = new WorkshopEntities())
    {
        MessageLog log = new MessageLog();
        log.Date = DateTime.Now;
        log.Type = (int)MessageLogType.Information;
        log.Message = "Logged In";
        log.CustomMessage = notifymessage.ToString();
        log.UserEmail = httpcontext.User.Identity.Name ?? "N/A";
        log.Address= HttpContext.Current.Request.UserHostAddress;
        context.MessageLogs.Add(log);

        try
        {
            context.SaveChanges();
        }
        catch (Exception ex)
        {
            ErrorLogger.LogError(ex);
        }
    }
}

So, far what I understand that PasswordSignInAsync task didn't complete and I am trying to fetch the information that is still not available.

I don't know it is a best approach or not but I am trying to log the user information at the time of user try to login.

Since the user has successfully logged in, you could retrieve the Username from the model itself.

Other user information can be obtained as such:

var userName = model.Username;
ApplicationUser user = UserManager.FindByName(userName);
string userid = user.UserId.ToString();
//Email
//Other properties...
