Thanks to #Simon C.
So, based on your comments, you have a POST contact method, but no way to navigate to the page yet ( just navigating to home/contact in your browser will send a GET request and since you have a [HttpPost] attribute, the route won't match). I think you need to add a GET method to your home controller to get you there:
[HttpGet]
public ActionResult Contact()
{
return View(new EmailFormModel());
}
This means when you first navigate to /home/contact, you will hit the above method. When you post your form back to your site, you will hit the Contact Method marked with [HttpPost].
Edit: As an aside, you will also need to add a method called Sent on your controller for when the email is sent successfully. The line return RedirectToAction("Sent"); will be looking for a method called Sent.

In EmailFormModel.cs model:
using System.ComponentModel.DataAnnotations;
using System.Web;
namespace MVCEmail.Models
{
public class EmailFormModel
{
[Required, Display(Name="Your name")]
public string FromName { get; set; }
[Required, Display(Name = "Your email"), EmailAddress]
public string FromEmail { get; set; }
[Required]
public string Message { get; set; }
public HttpPostedFileBase Upload { get; set; }
}
}
Change class Contact in HomeController.cs to:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Contact(EmailFormModel model)
{
if (ModelState.IsValid)
{
var body = "<p>Email From: {0} ({1})</p><p>Message:</p><p>{2}</p>";
var message = new MailMessage();
message.To.Add(new MailAddress("name#gmail.com")); //replace with valid value
message.Subject = "Your email subject";
message.Body = string.Format(body, model.FromName, model.FromEmail, model.Message);
message.IsBodyHtml = true;
if (model.Upload != null && model.Upload.ContentLength > 0)
{
message.Attachments.Add(new Attachment(model.Upload.InputStream, Path.GetFileName(model.Upload.FileName)));
}
using (var smtp = new SmtpClient())
{
await smtp.SendMailAsync(message);
return RedirectToAction("Sent");
}
}
return View(model);
}
And alter the Contact view (Views\Home\Contact.cshtml):
#model MVCEmail.Models.EmailFormModel
#{
ViewBag.Title = "Contact";
}
<h2>#ViewBag.Title.</h2>
#using (Html.BeginForm("Contact", "Home", null, FormMethod.Post, new {enctype = "multipart/form-data"}))
{
#Html.AntiForgeryToken()
<h4>Send your comments.</h4>
<hr />
<div class="form-group">
#Html.LabelFor(m => m.FromName, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.TextBoxFor(m => m.FromName, new { #class = "form-control" })
#Html.ValidationMessageFor(m => m.FromName)
</div>
</div>
<div class="form-group">
#Html.LabelFor(m => m.FromEmail, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.TextBoxFor(m => m.FromEmail, new { #class = "form-control" })
#Html.ValidationMessageFor(m => m.FromEmail)
</div>
</div>
<div class="form-group">
#Html.LabelFor(m => m.Message, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
#Html.TextAreaFor(m => m.Message, new { #class = "form-control" })
#Html.ValidationMessageFor(m => m.Message)
</div>
</div>
<div class="form-group">
#Html.LabelFor(m => m.Upload, new { #class = "col-md-2 control-label" })
<div class="col-md-10">
<input type="file" name="upload" />
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" class="btn btn-default" value="Send" />
</div>
</div>
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
And Webconfig.cs is:
<system.net>
<mailSettings>
<smtp from="you#outlook.com">
<network host="smtp-mail.outlook.com"
port="587"
userName="you#outlook.com"
password="password"
enableSsl="true" />
</smtp>
</mailSettings>
</system.net>
