Why does code execution stop at the line of adding to the database (C#, EF6)?

Question

C++ / C#

Program.cs code

using System;

namespace FirstEF6App {
    class Program {
        static void Main(string[] args) {
            using (UserContext db = new UserContext()) {

                User user1 = new User { Name = "Tom", Age = 33 };
                User user2 = new User { Name = "Sam", Age = 26 };
                //Прошелся пошаговым выполнение, на 15 строке вызываеться консоль и все...Дальше выполнение не идет
                db.Users.Add(user1);
     //           db.Users.Add(user2);
                db.SaveChanges();
                Console.WriteLine("Обьекты успешно сохранены");

                var users = db.Users;
                Console.WriteLine("Список обьектов");
                foreach (User u in users) {
                    Console.WriteLine("{0}.{1} - {2}", u.Id, u.Name, u.Age);
                }
            }
            Console.ReadLine();
        }
    }
}

User.cs code

namespace FirstEF6App {
    public class User {
        public int Id { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
    }
}

Code UserContext.cs

using System.Data.Entity;

namespace FirstEF6App {
    class UserContext : DbContext {

        public UserContext()
            : base("DbConnection") { }

        public DbSet<User> Users { get; set; }

    }
}

App.config code

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

I found a solution, it turns out you can’t name the table “User”, I don’t understand why, maybe after the update (maybe I just didn’t know before :)) they reserved this word and something else, but I have it. with the CodeFirst approach. just a table with that name should be generated and now
