asp net mvc sendgrid account email verification

Question

I'm trying to send automatic email to user to complete registration, I'm testing my app on local host

this is my Register Controller :

// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            //  Comment the following line to prevent log in until the user is confirmed.
            //  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>");

            // Uncomment to debug locally 
            // TempData["ViewBagLink"] = callbackUrl;

            ViewBag.Message = "Check your email and confirm your account, you must be confirmed "
                            + "before you can log in.";

            return View("Info");
            //return RedirectToAction("Index", "Home");


        }
        AddErrors(result);
    }

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

this is my Email service class

 public class EmailService : IIdentityMessageService
{
    public async Task SendAsync(IdentityMessage message)
    {
        // Create the email object first, then add the properties.
        var myMessage = new SendGridMessage();

        // this defines email and name of the sender
        myMessage.From = new MailAddress("no-reply@example.info", "My Example Admin");

        // set where we are sending the email
        myMessage.AddTo(message.Destination);

        myMessage.Subject = message.Subject;

        // make sure all your messages are formatted as HTML
        myMessage.Html = message.Body;

        // Create credentials, specifying your SendGrid username and password.
        var credentials = new NetworkCredential(
             ConfigurationManager.AppSettings["SendGridLogin"],
             ConfigurationManager.AppSettings["SendGridPassword"]
                                                );

        // Create an Web transport for sending email.
        var transportWeb = new Web(credentials);

        // Send the email.
        await transportWeb.DeliverAsync(myMessage);
    }
}

I'm using SendGridSmtpApi 1.3.1 & SendGrid C# cilent library 6.3.4 . Where is the problem , why this don't work ?

Ok. I'm not sure if you can send e-mail using just the credentials, you might have to create an ApiKey on your SendGrid account. Personally I send using only the ApiKey, like this: var transportWeb = new SendGrid.Web(); — severin, Mar 08 '16 at 11:45
Sorry, the braces were just to point to where the ApiKey goes, it's just a regular string value. Like this: var transportWeb = new SendGrid.Web("SG.pPBVADWWawd21Eawdwad"); — severin, Mar 08 '16 at 12:20
I've implemented this, like so: var apiKey = "apikeystring"; var transportWeb = new SendGrid.Web(apiKey); and it still don't works — joint_ops, Mar 08 '16 at 12:38
Is the domain you are attempting to send from registered on your SendGrid account? — severin, Mar 08 '16 at 12:54

Because you are making an asynchronous call, it is possible your program is exiting before the call a chance to complete. Therefore, the following is necessary if you would like to block until the call is complete, before your program proceeds:

transportWeb.DeliverAsync(message).Wait();

Alternatively, you can "Wait() or Result" from the calling function depending on your desired result.

For more information, check out the following:

What happens while waiting on a Task's Result?

Await on a completed task same as task.Result?

While this code may answer the question, providing additional context regarding *why* and/or *how* this code answers the question improves its long-term value. – Benjamin W. Mar 11 '16 at 06:50

Thanks for the follow up Benjamin! I've edited my answer to hopefully be more helpful. – Elmer Thomas Mar 12 '16 at 16:05
