SqlNotificationRequest uses SqlDependency internally to subscribe to query events. I would use SqlNotificationRequest over SqlDependency because most of the wiring is already done and it is meant to make using notifications easier. Technically because one uses the other internally, there is no difference in the two, just one has a lot of the setup work done.

Solution 2

In case of SQLDependency/SQLNotificationRequest you require separate queue per process. If your different processes listen on the same queue then event notification is not guaranteed. But this is how it is right now.
