2name: dotnet-backend-patterns
3description: Master C#/.NET backend development patterns for building robust APIs, MCP servers, and enterprise applications. Covers async/await, dependency injection, Entity Framework Core, Dapper, configuration, caching, and testing with xUnit. Use when developing .NET backends, reviewing C# code, or designing API architectures.

7 
8Master C#/.NET patterns for building production-grade APIs, MCP servers, and enterprise backends with modern best practices (2024/2025).
9 
10## Use this skill when
11 
12- Developing new .NET Web APIs or MCP servers
13- Reviewing C# code for quality and performance
14- Designing service architectures with dependency injection
15- Implementing caching strategies with Redis
16- Writing unit and integration tests
17- Optimizing database access with EF Core or Dapper
18- Configuring applications with IOptions pattern
19- Handling errors and implementing resilience patterns
20 
21## Do not use this skill when
22 
23- The project is not using .NET or C#
24- You only need frontend or client guidance
25- The task is unrelated to backend architecture
26 
27## Instructions
28 
29- Define architecture boundaries, modules, and layering.
30- Apply DI, async patterns, and resilience strategies.
31- Validate data access performance and caching.
32- Add tests and observability for critical flows.
33- If detailed patterns are required, open `resources/implementation-playbook.md`.
