dotnet-contribution-dotnet-backend-patterns

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. Use when: the task directly matches dotnet backend patterns responsibilities within plugin dotnet-contribution. Do not use when: a more specific framework or task-focused skill is clearly a better match.
