Getting Started With NATS JetStream in .NET

This article explains why NATS JetStream is a compelling alternative to traditional message brokers like RabbitMQ or Azure Service Bus for .NET developers. It covers the difference between Core NATS (fire-and-forget pub/sub) and JetStream (persistent, durable queue with at-least-once delivery), highlighting benefits such as small footprint (~18 MB server image), high performance (millions of messages per second), low resource usage, and flexible per-stream storage policies. The guide includes step-by-step setup instructions using Docker Compose with JetStream enabled, NuGet package installation (NATS.Net and NATS.Extensions.Microsoft.DependencyInjection), and code examples for configuring the NATS client and JetStream context in a .NET application's Program.cs.
