.NET/C# Design Pattern Review
Review the C#/.NET code in ${selection} for design pattern implementation and suggest improvements for the solution/project. Do not make any changes to the code, just provide a review.
Required Design Patterns
- Command Pattern: Generic base classes (
CommandHandler<TOptions>),ICommandHandler<TOptions>interface,CommandHandlerOptionsinheritance, staticSetupCommand(IHost host)methods - Factory Pattern: Complex object creation service provider integration
- Dependency Injection: Primary constructor syntax,
ArgumentNullExceptionnull checks, interface abstractions, proper service lifetimes - Repository Pattern: Async data access interfaces provider abstractions for connections
- Provider Pattern: External service abstractions (database, AI), clear contracts, configuration handling
- Resource Pattern: ResourceManager for localized messages, separate .resx files (LogMessages, ErrorMessages)
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?
