Official C# support for Visual Studio Code
01Result
dotnet/vscode-csharp ↗dotnet/vscode-csharp AI coding statistics: 30.4%
Adoption is broad. Many contributors are committing agent-authored work, which is what a real organisational rollout looks like.
02Drivers
What shapes this result
Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.
Assisted or autonomous
Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached.

04Method
What entered the denominator
The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.
Exclusion ledger
| Commits in window | 790 |
| Merge commits removed | −276 |
| CI / dependency bots removed | −31 |
| Considered | 483 |
Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.

Deterministic signature matching; no code-style inference. Squash merges can remove trailers, so this result remains a measured floor.
