Record Exception does not happen out of the box.

Hi

It might look like a detail, but after I instrumented my AspNetCore application to record exception, this still didn't happend.

tracerProviderBuilder.AddAspNetCoreInstrumentation(options =>
{
     options.RecordException = true;
});

I still have to add an asp.net ExceptionHandler where I record the exception, like mentioned below. This is not really the behavior that I expected, but it might be by design.

        app.UseExceptionHandler(exceptionHandlerApp =>
        {
            exceptionHandlerApp.Run(async context =>
            {
                // Get the triggered exception 
                var exceptionHandler = context.Features.Get<IExceptionHandlerFeature>();
                var exception = exceptionHandler.Error;

                // track it inside OpenTelemetry
                Activity.Current.RecordException(exception);
            });
        });

Is this normal behavior, or am I doing something wrong?

I am using .NET 6 LST.

@robvanpamel - Are you expecting exceptions handled inside app.UseExceptionHandler to be reported when you do options.RecordException = true? If Yes, then the behavior you are observing is by design. Exceptions handled in Middleware are not reported automatically even when you do options.RecordException = true. Only Unhandled exceptions are reported.
