dotnet-backend-patterns
Master C#/.NET patterns for building production-grade APIs, MCP servers, and enterprise backends with modern best practices (2024/2025).
About this skill
This skill provides comprehensive guidance on C#/.NET patterns and modern best practices (2024/2025) essential for building robust, scalable, and maintainable production-grade backend applications. It covers architectural design, performance optimization, testing strategies, and enterprise-level development for APIs, MCP servers, and other complex systems, ensuring solutions are aligned with the latest industry standards.
Best use case
To design, develop, review, and optimize C#/.NET backend applications, including Web APIs, MCP servers, and enterprise systems, adhering to modern best practices and architectural patterns.
Master C#/.NET patterns for building production-grade APIs, MCP servers, and enterprise backends with modern best practices (2024/2025).
High-quality, well-structured, performant, secure, and maintainable C#/.NET backend code. The agent will provide expert architectural guidance, suggest optimal patterns, assist in debugging, or generate code snippets that align with modern best practices, leading to more robust and scalable solutions.
Practical example
Example input
Design a robust ASP.NET Core Web API structure for an e-commerce platform. The API needs to handle product catalog, order processing, and user authentication. Include best practices for dependency injection, error handling, caching with Redis, and database interaction using Entity Framework Core. Provide code examples for a product service and controller.
Example output
The agent would generate a detailed architectural outline for the e-commerce API, proposing a clean architecture or layered approach. It would provide C# code snippets for setting up dependency injection in `Program.cs`, a global exception handling middleware, an interface and implementation for `IProductService`, a `ProductsController`, and an EF Core `DbContext` with example entities and migrations. It would also suggest specific Redis caching strategies for product data and explain how to write unit and integration tests for the service layer, all while adhering to the specified modern best practices.
When to use this skill
- Developing new C#/.NET Web APIs or MCP servers from scratch.
- Reviewing existing C# codebases for quality, security, performance, and adherence to modern patterns.
- Designing service architectures that incorporate dependency injection, modularity, and scalability principles.
- Implementing efficient data caching strategies using technologies like Redis.
When not to use this skill
- Developing frontend user interfaces or client-side applications (e.g., React, Angular, Vue.js).
- Working with non-C# or non-.NET programming languages and frameworks (e.g., Java, Python, Node.js).
- Performing basic scripting tasks that do not require complex architectural patterns or enterprise considerations.
- Troubleshooting network infrastructure, hardware issues, or operating system-level problems.
