Problems when implementing Authorization in Forms mode in MVC 5?

Question

ASP.NET

Good evening everyone. I'm learning ASPNet MVC5 based on reading Metanit and implementing a small pet project - sort of HH but in a very simplified form.
There was a problem creating the "Applicant" authentication system in Forms mode.
1. Enabled Forms authentication in the web.config file:

<authentication mode="Forms">
                       <forms name="cookies" timeout="2880" loginUrl="~/Home/Index" />
                 </authentication>

2. Also added a connection string for EntityFramework in the web.config file:

<add name="JobSeekerRegistrationContext" connectionString="Data Source= 
                         (LocalDB)\MSSQLLocalDB;AttachDbFilename='|DataDirectory|\FormsAuthJobSeeker.mdf'; Initial 
                          Catalog=FormsAuthJobSeeker;Integrated Security=True"

3. Created the "Applicant" model:

public class JobSeeker
                        {
                        //Идентификационный номер соискателя
                       public int JobSeekerID { get; set; }

                       //Фамилия соискателя
                      public string LastName { get; set; }

                      //Имя соискателя
                     public string FirstName { get; set; }

                     //Электронная почта
                    public string Email { get; set; }
                    
                    //Пароль
                   public string Password { get; set; }
                   }

4. I create a data context for interacting with the database:

public class JobSeekerContext: DbContext
                       {
                       public JobSeekerContext():base("JobSeekerRegistrationContext") { }
                       public DbSet<JobSeeker> JobSeekers { get; set; }
                        }

5. I create a model for applicant registration:

public class JobSeekerRegistration
                      {
        
                     //фамилия соискателя
                    [Required]
                    public string LastName { get; set; }

                   //Имя соискателя
                  [Required]
                  public string FirstName{ get; set; }

                 //Почта
                [Required]
                public string Email { get; set; }

               //Пароль
               [Required]
               [DataType(DataType.Password)]
               public string Password { get; set; }
               }

6.Created a form for registration of the "Applicant". The form is a modal window in
the Index view, which is the home page of my application. When you click on the
Register button, this modal window will be displayed:

<form id="authtorization_joobseeker_form" action="/JobSeekerAccount/Register" method="post">
                <p id="last_name">
                    <label id="joobseeker_last_name" for="joobseeker_last_name">Фамилия</label>
                    <input id="joobseeker_last_name" type="text" name="LastName">
                </p>
                <p id="first_name">
                    <label id="joobseeker_first_name" for="joobseeker_first_name">Имя</label>
                    <input id="joobseeker_first_name" type="text" name="FirstName">
                </p>
                <p id="mail">
                    <label id="joobseeker_mail" for="joobseeker_mail">Email</label>
                    <input id="joobseeker_mail" type="mail" name="Email">
                </p>
                <p id="password">
                    <label id="joobseeker_password" for="joobseeker_password">Пароль</label>
                    <input id="joobseeker_password" type="password" name="Password">
                </p>
                <input id="authtorization_joobseeker_submit" class="submit" type="submit" value="Регистрация">
            </form>

7. Created a JobSeekerAccount controller with the Register method, which should receive data
from the POST request, which is presented above and save the information in the database:

public class JobSeekerAccount : Controller
                  {
                  // GET: JobSeekerAccount

                  [HttpPost]
                  public ActionResult Register(JobSeekerRegistration model)
                  {
                  if (ModelState.IsValid)
                  {
                   JobSeeker jobSeeker = null;
                   using (JobSeekerContext db = new JobSeekerContext())
                   {
                    jobSeeker = db.JobSeekers.FirstOrDefault(JobSeeker => JobSeeker.LastName == model.LastName);
                   } 
                   if (jobSeeker==null)
                   {
                    using (JobSeekerContext db = new JobSeekerContext())
                    {
                        db.JobSeekers.Add(new JobSeeker { LastName = model.LastName, FirstName = model.FirstName, Email = model.Email, Password = model.Password });
                        db.SaveChanges();
                        jobSeeker = db.JobSeekers.Where(JobSeeker => JobSeeker.Email == model.Email && JobSeeker.Password == model.Password).FirstOrDefault();
                    }
                    if (jobSeeker != null)
                    {
                        FormsAuthentication.SetAuthCookie(model.Email, true);
                        return RedirectToAction("Index", "Home");
                    }    
            }    
            return View(model);

8. The assembly is assembled without errors. After entering the data and submitting the form, the following error is displayed:

Server error in application '/'.
Could not find this resource.

Most likely it's the controller, it doesn't have the right ending, the article has a description of why this is so

Answer 2

Startup.cs show
most likely did not miss the stage with routing
