Я переношу ASP.NET Веб-API 2 сервис для ASP.NET Core 3.1 Web API, и я уже разрешил все зависимости и проблемы, но я не получаю сигнал.

Странные вещи:

• Я могу подключиться, но получаю какое-либо сообщение: подключение к консоли Chrome
• Идентификатор этого соединения всегда равен 0 (в asp.net фреймворк, всегда был уникальным кодом)
• Я ввел пользовательскую авторизацию в концентратор:

Код:

 using Flow2.Api.Security;
using Microsoft.AspNetCore.SignalR;

namespace Flow2.Api.Hubs
{
    [AuthorizeSignalR]
    public class HubNotification : Hub
    {
        public void Notificar()
        {
            Clients.All.SendAsync("broadcastMessage", "oi", "olá");
        }
    }
}
  

С точкой останова, но точка останова не попадает: печать авторизации с точкой останова
