Dotnet Design Pattern Review

Review Checklist

• Design Patterns: Identify patterns used. Are Command Handler, Factory, Provider, and Repository patterns correctly implemented? Missing beneficial patterns?
• Architecture: Follow namespace conventions ({Core|Console|App|Service}.{Feature})? Proper separation between Core/Console projects? Modular and readable?
• .NET Best Practices: Primary constructors, async/await with Task returns, ResourceManager usage, structured logging, strongly-typed configuration?
• GoF Patterns: Command, Factory, Template Method, Strategy patterns correctly implemented?
• SOLID Principles: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion violations?
• Performance: Proper async/await, resource disposal, ConfigureAwait(false), parallel processing opportunities?
• Maintainability: Clear separation of concerns, consistent error handling, proper configuration usage?
• Testability: Dependencies abstracted via interfaces, mockable components, async testability, AAA pattern compatibility?
• Security: Input validation, secure credential handling, parameterized queries, safe exception handling?
• Documentation: XML docs for public APIs, parameter/return descriptions, resource file organization?
• Code Clarity: Meaningful names reflecting domain concepts, clear intent through patterns, self-explanatory structure?
• Clean Code: Consistent style, appropriate method/class size, minimal complexity, eliminated duplication?

Improvement Focus Areas

• Command Handlers: Validation in base class, consistent error handling, proper resource management
• Factories: Dependency configuration, service provider integration, disposal patterns
• Providers: Connection management, async patterns, exception handling and logging
• Configuration: Data annotations, validation attributes, secure sensitive value handling
• AI/ML Integration: Semantic Kernel patterns, structured output handling, model configuration

Provide specific, actionable recommendations for improvements aligned with the project's architecture and .NET best practices.
