You’ve got critical .NET applications still running on .NET Framework or early .NET Core—and a backlog that never leaves room for modernization. In this session, we’ll explore how the GitHub Copilot app modernization agent can help you upgrade those apps to modern .NET and prepare them for Azure, in days instead of months.

We’ll start with a realistic legacy .NET solution and ask Copilot to analyze it, generate a modernization plan, and create a working branch. Along the way, you’ll see how the agent updates project files, fixes common API changes, iterates through build and test failures, and surfaces a clear summary of what changed.

But this is not an AI magic show. We’ll also look at where the agent struggles, where architectural judgment still matters, and how to wrap the tooling in a safe, test-driven process. You’ll leave with a practical playbook for combining proven modernization strategies with GitHub Copilot’s new agents to accelerate your journey from legacy .NET to modern, cloud-ready applications.
