The official .NET client library for Apache Pulsar.
DotPulsar is written entirely in C# and implements Apache Pulsar's binary protocol.
Have a look at the changelog.
Let's take a look at a “Hello world” example, where we first produce a message and then consume it.
First, we need a Pulsar setup. Have a look here to see how to setup a local standalone Pulsar instance. Install the NuGet package DotPulsar and copy/paste the code below (you will be needing using declarations for ‘DotPulsar’ and ‘DotPulsar.Extensions’).
const string myTopic = "persistent://public/default/mytopic"; await using var client = PulsarClient.Builder() .Build(); // Connecting to pulsar://localhost:6650 await using var producer = client.NewProducer(Schema.String) .Topic(myTopic) .Create(); _ = await producer.Send("Hello World"); // Send a message and ignore the returned MessageId await using var consumer = client.NewConsumer(Schema.String) .SubscriptionName("MySubscription") .Topic(myTopic) .Create(); await foreach (var message in consumer.Messages()) { Console.WriteLine($"Received: {message.Value()}"); await consumer.Acknowledge(message); }

Help prioritizing the roadmap is most welcome, so please reach out and tell us what you want and need.
Apache Pulsar has a Slack instance and there you'll find us in the #dev-dotpulsar channel.
