Introducing Nimbus, open source messaging in .net

Deep dive into a 13-year-old message bus library still running in production, you'll learn async messaging patterns and see what makes it work at scale.

Damian returns to walk through Nimbus, a .NET message bus library that's spent 13 years quietly handling millions of transactions in production systems despite minimal public visibility. You'll understand why asynchronous messaging has become essential for distributed systems, see concrete examples of how it's solved real-world problems, and get a live demo of what's new in the 2026 relaunch. The talk covers the library's origins and evolution, giving you both the design thinking behind it and practical knowledge for implementing async patterns in your own work. Stick around for the quiz if you want a shot at one of two JetBrains licenses.
