    EF Core, SignalR and Database Change Notifications


      Is this possible?  I haven't been able to find documentation on how to get this to work.  We're wanting to use SignalR within our application.

          I can't think of a way to use EF Core and DB Change Notification directly together easily. EF Core uses generic ADO.NET APIs. It can't access ODP.NET-specific APIs. DB Change Notification is specific to ODP.NET.


          You could execute a query with EF Core. Then, capture the SQL executed and re-execute it with ODP.NET so that it can be registered with DB Change Notification. You don't need to actually retrieve the results in the re-execution. When a change occurs, the event handler will have EF Core query again to retrieve the new data..
