Overview

C# language patterns, coding standards, and .NET runtime features for idiomatic, performant code. This consolidated skill spans 25 topic areas. Load the appropriate companion file from references/ based on the routing table below.

Always-Load Baseline

These references define correctness and quality standards that apply to all C# code — load them by default whenever producing or reviewing code, regardless of what the user asked for:

• references/coding-standards.md — naming conventions, file layout, style rules
• references/async-patterns.md — async/await correctness, ConfigureAwait, cancellation propagation (nearly all .NET code uses async)
• references/solid-principles.md — SOLID, DRY, single responsibility, dependency inversion, anti-pattern detection
• references/code-smells.md — common mistakes the agent should avoid without being told (async void, DI lifetime misuse, swallowed exceptions)
• references/dotnet-releases.md — .NET 10/11 and C# 14/15 features, version matrix, TFM-specific code generation rules (compensates for training data cutoff)
