Master C#/.NET patterns for building production-grade APIs, MCP servers, and enterprise backends with modern best practices (2024/2025). - 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 - Use async/await all the way through the call stack - Inject dependencies through constructor injection - Use IOptions for typed configuration - Return Result types instead of throwing exceptions for business logic - Use CancellationToken in all async methods - Prefer Dapper for read-heavy, performance-critical queries - Use EF Core for complex domain models with change tracking - Cache aggressively with proper invalidation strategies - Write unit tests for business logic, integration tests for APIs - Use record types for DTOs and immutable data - Don't block on async with .Result or .Wait() - Don't use async void except for event handlers - Don't catch generic Exception without re-throwing or logging - Don't hardcode configuration values - Don't expose EF entities directly in APIs (use DTOs) - Don't forget AsNoTracking() for read-only queries - Don't...
