Dotnet Backend Patterns

This is a solid reference for building production .NET backends with modern C# patterns. It covers the essentials: dependency injection, async/await, caching with Redis, EF Core and Dapper usage, the IOptions pattern, and resilience strategies. The skill includes a detailed implementation playbook and emphasizes testing and observability. Use it when architecting APIs or MCP servers, doing code reviews, or optimizing database access. It's not trying to be exhaustive, but it gives you concrete architectural guidance and reminds you to validate performance and add tests where it matters. Good for mid-level to senior devs who want consistency across enterprise projects.
