Why 'insert' trigger three TableChangedEvent?

[dcuti8]

I use the example code, but when i insert data in SSMS, the TableChangedEvent trigger three times in this order --- NotificationType.None, NotificationTypes.Update, NotificationTypes.Insert.

I want to monitor update, insert, delete event, when I delete and update data in SSMS it works perfectly. Just the insert trigger three times...

`var listener = new SqlDependencyEx(connectionString, "DatabaseName", "TableName");

listener.TableChanged += (o, e) =>
{
//logic code
};

listener.Start();`

Thanks for any reply!
