GitHub moved the Copilot runtime to Rust 🚀
GitHub migrated the runtime behind Copilot to Rust, and used Copilot during the migration itself.
✅ Why this is worth reading:
• Runtime work is systems work: a language migration means tracing real production behavior, not just translating syntax.
• Copilot was part of the workflow: useful for exploring an unfamiliar codebase, drafting changes, and keeping momentum through repetitive conversion work.
• The output still needs engineering judgment: boundaries, performance, correctness, and rollout safety are not autocomplete problems.
This is a practical case study for teams asking where coding agents help on a large refactor. Use them to accelerate investigation and implementation. Keep humans on architecture, tests, and production checks.

Migrating the GitHub Copilot runtime to Rust, using Copilot
A rewrite this size wasn't affordable before agents. Here's what porting the Copilot agent runtime to 800,000 lines of production Rust actually took.
GitHub improved the Copilot code review flow 🔥
GitHub shipped an improved Copilot code review experience. That matters most on the boring, high-volume PRs where reviewers need help finding a real issue, not another summary of changed files.
For C# teams, use Copilot review as an extra pass on every ASP.NET, EF Core, and library PR. Then keep the human review focused on contracts, failure behavior, and whether the change belongs in the codebase.
Practical rule:
• Let Copilot flag suspicious diffs.
• Do not merge because it found nothing.
• Keep analyzers and tests as the enforcement layer.
AI review is cheap coverage. It is not a replacement for someone who knows why that nullable property or cancellation token exists.

Copilot code review now gives you a clearer view of how a review changes over time, more intelligently auto-resolves its own suggestions, and generates useful commit messages when you accept…
AI is changing the developer career ladder 🚀
GitHub's latest developer career advice is refreshingly practical: AI can write more of the first draft, but it cannot own the engineering outcome for you.
The skills to double down on:
• Systems thinking: understand the service, data flow, failure modes, and tradeoffs around the code.
• Judgment: spot the plausible-looking AI patch that breaks security, cost, or production behavior.
• Communication: turn a vague product request into constraints an agent, teammate, and reviewer can act on.
Using Copilot or an agent is becoming normal. Being the person who can frame the task, verify the output, and ship it safely is still the hard part.
