http://johnatten.com/2014/04/20/asp-net-identity-2-0-setting-up-account-validation-and-two-factor-authorization/#Testing-Account-Confirmation-Using-the-Email-Service

here is the code i used in sendemail :

public class EmailService : IIdentityMessageService
    {
        public Task SendAsync(IdentityMessage message)
        {
            // Credentials:
            var credentialUserName = "fiazranjha@outlook.com";
            var sentFrom = "fiazranjha@outlook.com";
            var pwd = "mypasswordstring";                    //my actual password is different

            // Configure the client:
            System.Net.Mail.SmtpClient client =
                new System.Net.Mail.SmtpClient("smtp-mail.outlook.com");

            client.Port = 587;
            client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            client.UseDefaultCredentials = false;

            // Creatte the credentials:
            System.Net.NetworkCredential credentials =
                new System.Net.NetworkCredential(credentialUserName, pwd);

            client.EnableSsl = true;
            client.Credentials = credentials;

            // Create the message:
            var mail =
                new System.Net.Mail.MailMessage(sentFrom, message.Destination);

            mail.Subject = message.Subject;
            mail.Body = message.Body;

            // Send:
             return client.SendMailAsync(mail);



            // Plug in your email service here to send an email.
          // return Task.FromResult(0);                                          // i commented out this line because it is not available in john atten article

}

account controller actions for register and confirmemail are as follows:

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = new ApplicationUser { UserName = model.UserName,PhoneNumber=model.PhoneNumber, Email = model.Email };
                var result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {
                    await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
                    
                    // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                    // Send an email with this link
                     string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                     var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                     await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                    return RedirectToAction("Index", "Home");
                }
                AddErrors(result);
            }

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

        //
        // GET: /Account/ConfirmEmail
        [AllowAnonymous]
        public async Task<ActionResult> ConfirmEmail(string userId, string code)
        {
            if (userId == null || code == null)
            {
                return View("Error");
            }
            var result = await UserManager.ConfirmEmailAsync(userId, code);
            return View(result.Succeeded ? "ConfirmEmail" : "Error");
        }

//             
 //confirmemail view  is here confirmemail.cshtml

@{
    ViewBag.Title = "Confirm Email";
}

<h2>@ViewBag.Title.</h2>
<div>
    <p>
        Thank you for confirming your email. Please @Html.ActionLink("Click here to Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })
    </p>
</div>

i will be thankful in advance if you help me for outlook or gmail smtp because sendgrid is not free.
