.net core 3.1 remote debugging from VS 2019 CE to Raspberry PI - vsdbg exits when the app wants to handle a GPIO-interrupt

My App handles GPIO interrupts on a Raspberry PI 3B+ using the Unosquare.Raspberry.IO and Unosquare.WiringPi nuget packages. Since it has to handle multiple interrupts, it sets up a task for each of them and then waits on the resulting task list.

The setup for the interrupt is as follows:

   public async Task StartCounterAsync(CancellationToken cancelToken)
    {
        logger.LogInformation($"Starting Counter {counterName}");

        var counterPin = Pi.Gpio[inputPin];
        counterPin.PinMode = GpioPinDriveMode.Input;

        counterPin.RegisterInterruptCallback(EdgeDetection.RisingEdge, HandleCounterInterrupt);

        await cancelToken;
    }

    private void HandleCounterInterrupt()
    {
        logger.LogInformation("HandleCounterInterrupt");
    }
}

When I launch the application via ssh on the raspi, the application runs fine and the interrupt handling works without any problems. If I launch the application via "DebugAdapterHost.Launch /LaunchJson:launch.json" it runs fine until I press the button to create the interrupt. Then vsdgb simply exits:

 1> [DebugAdapter] <--   E (thread): {"seq":97,"type":"event","event":"thread","body":{"reason":"started","threadId":1340}}
*** Here I press the button ***
 1> [DebugAdapter] <--   E (exited): {"seq":98,"type":"event","event":"exited","body":{"exitCode":0}}
 1> [DebugAdapter] <--   E (terminated): {"seq":99,"type":"event","event":"terminated","body":{}}
 1> [DebugAdapter] --> C (disconnect-15): {"type":"request","command":"disconnect","arguments":{},"seq":15}

I have tried this with vsdbg running as a normal user and running as root with the same result. This is no crash, vsdbg just exits. A breakpoint inside HandleCounterInterrupt() is never reached.

Environment:

• Raspberry 3 with raspbian
• .net core 3.1.4 and vsdbg installed according to this:

  and Scott Hanselman suggestions:
