.NET Clinic — paste the C#, get the best-practices review

Paste modern C# (.NET 8+) and get the review a staff engineer would leave on the pull request: which shape the code is — ASP.NET Core service, console/worker, class library or test project — a ship-it / tidy-first / rework verdict, and findings that quote a verbatim line from your own code. A free browser-side analyser lexes the source first (comments, strings, verbatim and interpolated literals blanked so nothing false-matches), detects the shape from weighted evidence rather than guessing, and runs thirty-two deterministic rules — async void, blocking .Result, empty and broad catches, throw ex, per-call HttpClient, undisposed disposables, interpolated log messages, SQL assembled from strings, hardcoded secrets, static mutable state, magic numbers, deep nesting. The AI review must then adjudicate every one of those as confirmed or set aside, and every quote it makes is checked against your source. A derived work of @github/dotnet-best-practices from the open-source awesome-copilot collection (MIT).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
