Dave Mason writes a custom app to read extended events data:
It took me a while to make the transition from SQL Profiler to Extended Events. Eventually I got comfortable enough with it to use it 100% of the time. As I read more about the XEvents architecture (as opposed to just “using” XEvents), I gained a deeper appreciation of just how great the feature is. My only gripe is that there isn’t a way to handle the related events from within SQL Server using T-SQL. DDL triggers can’t be created for XEvents. And they can’t be targeted to Service Broker for Event Notifications (not yet, anyway). For now, the one way I know of to handle an XEvent is by accessing the event_stream target via the .NET framework. I’ll demonstrate with C#.
9/10, would have preferred F# but would read again.
