Csharp Expert

What it does

This skill provides expert-level guidance on C# development, specifically focusing on modern C# (version 12 and above), .NET 8+, ASP.NET Core, LINQ, asynchronous programming, and enterprise application development. It enables AI agents to generate clean, performant, and maintainable C# code adhering to industry best practices. The skill demonstrates features like primary constructors, collection expressions, record types (including immutable records, record classes with methods, and record structs), and pattern matching.

When to use it

• Generating C# code snippets for backend applications.
• Understanding and implementing modern C# language features (C# 12+).
• Troubleshooting existing C# code or identifying areas for improvement.
• Learning about best practices in .NET development, including LINQ and async programming.
• Creating data structures using record types and understanding their immutability.
