Hi Mates

 

I have this issue and dont know how to resolve it on my Register ActionResult, kindly please assist me.

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = new ApplicationUser() { UserName = model.UserName };
                user.Email = model.Email;
                user.ConfirmedEmail = false;
                var result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {



                    MailMessage msg = new MailMessage();

                    msg.From = new MailAddress("[email protected]");
                    msg.To.Add("[email protected]");
                    msg.Subject = "test";
                    msg.Body = "Test Content";

                    using (SmtpClient client = new SmtpClient())
                    {
                        client.EnableSsl = true;
                        client.UseDefaultCredentials = true;
                        client.Credentials = new NetworkCredential("[email protected]", "Mohali@5050");
                        client.Host = "smtp.gmail.com";
                        client.Port = 587;
                       // client.DeliveryMethod = SmtpDeliveryMethod.Network;

                        client.Send(msg);  // This gets thrown as an error, yes google settings are set all of them.
                    }

                    return RedirectToAction("Confirm", "Account", new { Email = user.Email });
                }
                else
                {
                    AddErrors(result);
                }
            }

            // If we got this far, something failed, redisplay form  478216
            return View(model);
        }
