Question

我正在尝试使用SqlDependencyEx，问题是OnDataChange事件没有在控制器内被触发，我已经启用了Service Broker。这是代码：

    private const string CONNECTION_STRING = "Server=LFTCMCPTP83;Database=Database;Trusted_Connection=True;MultipleActiveResultSets=true; Integrated Security=false;User ID=used_id;Password=password";
    private const string DATABASE_NAME = "db_name";
    private const string TABLE_NAME = "table_name";
    private const string SCHEMA_NAME = "dbo";
    private SqlDependencyEx sqlDependency = new SqlDependencyEx(CONNECTION_STRING, DATABASE_NAME,
    TABLE_NAME, SCHEMA_NAME);
    private void RegisterNotification()
    {
        sqlDependency.TableChanged += OnDataChange;
        sqlDependency.Start();
    }
    private void OnDataChange(object sender, SqlDependencyEx.TableChangedEventArgs e)
    {
        //Code
    }
    public IActionResult Create(){
         RegisterNotification();
    }

Controller内部的SqlDependencyEx事件未被触发
