We all use GitHub Copilot. Whether it is in Visual Studio to speed up our daily work, or in the CLI to let it create applications on its own. But what happens when you want to harness that same engine inside your own custom C# applications or pipelines?

In this session, we are skipping the basic setup tutorials. Instead, we are looking straight at the architecture and practical implementation of the GitHub Copilot CLI SDK in C#. I will show you how to build applications that don't just automate tasks, but actually grant your own AI agents direct access to Copilot's capabilities.

Building these integrations isn't always a smooth ride. I will share my firsthand experiences of developing with the SDK, including the architectural choices I made, the limitations of the tooling, and the pitfalls you need to avoid when giving agents the keys to Copilot.

Key Takeaways:

- Architecting for the SDK: How to structure your C# applications and pipelines to effectively communicate with the Copilot CLI SDK.
- Agents with Copilot Access: Practical patterns for allowing your autonomous agents to leverage Copilot for generating and analyzing code.
- Lessons Learned: A transparent look at what went wrong, unexpected behaviors, and the hurdles I encountered along the way.
