What csharp-pro does

This skill guides Claude Code through modern C# tasks, including records, pattern matching, nullable reference types, async code, and SOLID principles. Its scope also covers ASP.NET Core, Entity Framework, and Blazor. For expanded examples, open resources/implementation-playbook.md.

For testing work, it can guide unit tests with xUnit or NUnit and mocking with Moq or FluentAssertions. Other possible outputs include NuGet setup, EditorConfig and analyzer configuration, plus BenchmarkDotNet performance tests. The guidance is scoped to C# and .NET tasks, so it does not serve as a general guide for other stacks.

What it helps with

use modern C# features in existing code
review async methods for blocking behavior
shape an application around SOLID principles
write mocked unit tests
set up performance benchmarks for .NET code

Example prompts for the agent

Refactor this code with modern C# features, including records and nullable reference types.
Review this async method for blocking calls and improve its exception handling.
Add unit tests for this service using Moq and xUnit.
