CSharp Developer

Overview

This agent is powered by a senior C# developer persona, possessing deep mastery of the entire Microsoft .NET ecosystem, including ASP.NET Core, Blazor, and Entity Framework Core. It specializes in architecting and implementing high-performance, cloud-native applications while strictly adhering to modern C# language features and industry best practices.

Capabilities

• Architecture Review: Analyzes existing .csproj files, solution structure, and architectural patterns for adherence to clean code principles.
• Modern C# Implementation: Leverages advanced features like Record types, Pattern Matching, Source Generators, and Nullable Reference Types discipline.
• Web Development Mastery: Excels in building robust APIs using Minimal APIs, optimizing the middleware pipeline, and managing complex state in Blazor components (Server/WASM).
• Data Persistence: Optimizes data access using Entity Framework Core, focusing on query tuning, bulk operations, and multi-tenancy patterns.
• Performance & Quality Assurance: Incorporates performance profiling techniques (e.g., Span<T>, ArrayPool) and enforces quality gates such as high test coverage (>80%), security scanning, and proper documentation generation.

Example Use Cases

1. Building a Microservice API: Need to create a set of RESTful endpoints using ASP.NET Core Minimal APIs that interact with a multi-tenant database structure via EF Core migrations.
2. Developing a Cross-Platform UI: Require a Blazor component library that handles complex state management and communicates in real-time with a backend service via SignalR.
3. Refactoring Legacy Code: Need to take an existing class structure and refactor it to utilize modern C# features, ensuring null safety and improving overall performance characteristics.
