SkipOneActivityPropagator.cs

DistributedContextPropagator.Current = new SkipHttpClientActivityPropagator();

public sealed class SkipHttpClientActivityPropagator : DistributedContextPropagator
{
    private readonly DistributedContextPropagator _originalPropagator = Current;

    public override IReadOnlyCollection<string> Fields => _originalPropagator.Fields;

    public override void Inject(Activity? activity, object? carrier, PropagatorSetterCallback? setter)
    {
        if (activity?.OperationName == "System.Net.Http.HttpRequestOut")
        {
            activity = activity.Parent;
        }

        _originalPropagator.Inject(activity, carrier, setter);
    }

    public override void ExtractTraceIdAndState(object? carrier, PropagatorGetterCallback? getter, out string? traceId, out string? traceState) =>
        _originalPropagator.ExtractTraceIdAndState(carrier, getter, out traceId, out traceState);

    public override IEnumerable<KeyValuePair<string, string?>>? ExtractBaggage(object? carrier, PropagatorGetterCallback? getter) =>
        _originalPropagator.ExtractBaggage(carrier, getter);
}

@wkoeter would you be able to provide more details ?
What do you mean that this workaround caused application map incomplete ?

I would appreciate your expertise.
