数据库未创建代码优先EF

Question

我不明白为什么我的代码不起作用。我有一个模特：

    public class Client
    {
        public int Id { get; set; }
        public string Surname { get; set; }
    }

我有一个上下文：

    public class BetContext : DbContext
    {
        public BetContext()
            : base("name=Bet")
        {
        }
        public virtual DbSet<Client> Clients { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        }
    }

我的ConnectionString：

<connectionStrings>
    <add name="Bet" providerName="System.Data.SqlClient" connectionString="Data Source=PK01;     Initial Catalog=Bet;Integrated Security=True;     MultipleActiveResultSets=True" />
  </connectionStrings>

我的GlobalAsax：

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory());
            Database.SetInitializer(new  InitializerDb());
        }

我的ConnectToServer： ConnectToServer

我的初始化程序：

    public class InitializerDb : DropCreateDatabaseIfModelChanges<BetContext>
    {
        protected override void Seed(BetContext context)
        {
            var client = new List<Client>
            {
                new Client
                {
                    Id = 1 , Surname = "Lalala" , Name = "Paxan" , DateOfBirthday = DateTime.Now, Email = "lalll",
                    Password = "123445" , Phone = "12345"
                }
            };
            client.ForEach(s => context.Clients.Add(s));
            context.SaveChanges();
        }
    }

我被困住了。请告诉我为什么这段代码没有在SQL Server中创建新数据库？
