尝试创建 confluence.kafka 库

Question

I'm trying to create a Confluence Kafka layer for my console apps.

I installed Confluence Kafka NuGet package.

And in this code

private readonly Producer<Null, string> _producer;
private Consumer<Null, string> _consumer;

I have error

Cannot access internal class 'Producer' here (class) Confluent.Kafka.Producer A high level producer with serialization capability.

How I can solve this?

In new version of Confluence Kafka package Producer and Consumer are private classes. You must use ProducerBuilder and ConsumerBuilder to create them.

        _producerConfig = new ProducerConfig 
        {
            BootstrapServers = host
        };
        _producer = new ProducerBuilder<Null, string>(_producerConfig).Build();

        _consumerConfig = new ConsumerConfig
        {
            GroupId = "custom-group",
            BootstrapServers = host
        };
        _consumer = new ConsumerBuilder<Null, string>(_consumerConfig).Build();
