Creates a new instance of the SqlNotificationRequest class with default values.
Assembly: System.Data (in System.Data.dll)
If the default constructor is used to create a SqlNotificationRequest object, that instance must have its UserData and Options properties initialized before assigning the object to a SqlCommand object's Notification property. The default values used by the constructor are NULL (Nothing in Visual Basic) for the UserData, an empty string for the Options, and zero for the Timeout.
