ODP.NET

I am experimenting with MeterListener in my application, and using the following code:

    public class DiagnosticsService : BackgroundService
   {
       protected override async Task ExecuteAsync(CancellationToken stoppingToken)
       {
           using MeterListener meterListener = new();
           meterListener.InstrumentPublished = (instrument, listener) =>
           {
               if (instrument.Meter.Name == "Oracle.ManagedDataAccess.Core")
               {
                   listener.EnableMeasurementEvents(instrument);
                   Console.WriteLine($"{instrument.Name} registered");
               }
           };
           meterListener.SetMeasurementEventCallback<long>(OnMeasurementRecorded);
           meterListener.Start();
           try
           {
               await Task.Delay(-1, stoppingToken);
           }
           catch(TaskCanceledException)
           {
               Console.WriteLine("Finish processing");
           }
       }
       public static void OnMeasurementRecorded(Instrument instrument, T measurement, ReadOnlySpan<KeyValuePair<string, object?>> tags, object? state) where T : struct
       {
           Console.WriteLine($"Measurement recorded: {instrument.Name} - {measurement}");
       }
   }  

I can sucessfuly register all counters published by the Oracle Driver, but the OnMeasurementRecorded is never called.

Am I missing any aditional steps?

My ODP.Net version is 23.8.0 (the connection is accessed throught EF Core 8 provider)

Edit: Fixed the SetMeasurementEventCallback on the example above. The problem persists. Made the same test with other versions of the ODP.Net and OnMeasurementRecorded still not being called.
