Csharp Conventions
Use when a ticket adds or changes C#/.NET code — ASP.NET Core services, libraries, workers — and it must follow the repo's C# conventions — the .NET coding conventions, nullable reference types on and honoured, async all the way with cancellation tokens, dependency injection through the container with correct lifetimes, records for values, IDisposable and thread safety handled, Roslyn analyzers and dotnet format clean — as the language pack for any C# change. Invoke for "add this in C#", "fix the async void", "the nullable warnings", or when reviewing a .NET diff.

From the source SKILL.md
Modern C# puts nullability in the type system, values in records, and asynchrony in a first-class model with cancellation. Code that suppresses warnings, blocks on tasks, or news up its dependencies gives that back. For the builder and the reviewer of a .NET diff; the solution's config and existing code win over it.
