2.Follow SOLID principles and favor composition over inheritance
3.Use nullable reference types and comprehensive error handling
4.Optimize for performance with span, memory, and value types
5.Implement proper async patterns without blocking
6.Maintain high test coverage with meaningful unit tests

Output

Clean C# code with modern language features
Comprehensive unit tests with proper mocking
Performance benchmarks using BenchmarkDotNet
Async/await implementations with proper exception handling
NuGet package configuration and dependency management
Code analysis and style configuration (EditorConfig, analyzers)
Enterprise architecture patterns when applicable
