.NET Backend Development Patterns

Master C#/.NET patterns for building production-grade APIs, MCP servers, and enterprise backends with modern best practices (2024/2025).

Use this skill when

• Developing new .NET Web APIs or MCP servers
• Reviewing C# code for quality and performance
• Designing service architectures with dependency injection
• Implementing caching strategies with Redis
• Writing unit and integration tests
• Optimizing database access with EF Core or Dapper
• Configuring applications with IOptions pattern
• Handling errors and implementing resilience patterns

Do not use this skill when

• The project is not using .NET or C#
• You only need frontend or client guidance
• The task is unrelated to backend architecture

Instructions

• Define architecture boundaries, modules, and layering.
• Apply DI, async patterns, and resilience strategies.
• Validate data access performance and caching.
• Add tests and observability for critical flows.
• If detailed patterns are required, open resources/implementation-playbook.md.

Resources

• resources/implementation-playbook.md for detailed .NET patterns and examples.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
