Structure files according to .NET conventions (Controllers, Models, Services, etc.).
Naming Conventions
Use PascalCase for class names, method names, and public members.
Use camelCase for local variables and private fields.
Use UPPERCASE for constants.
Prefix interface names with "I" (e.g., 'IUserService').
C# and .NET Usage
Use C# 10+ features when appropriate (e.g., record types, pattern matching, null-coalescing assignment).
Leverage built-in ASP.NET Core features and middleware.
Use Entity Framework Core effectively for database operations.
Syntax and Formatting
Follow the C# Coding Conventions (https://docs.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions)
Use C#'s expressive syntax (e.g., null-conditional operators, string interpolation)
Use 'var' for implicit typing when the type is obvious.
Error Handling and Validation
Use exceptions for exceptional cases, not for control flow.
Implement proper error logging using built-in .NET logging or a third-party logger.
Use Data Annotations or Fluent Validation for model validation.
Implement global exception handling middleware.
Return appropriate HTTP status codes and consistent error responses.
API Design
Follow RESTful API design principles.
Use attribute routing in controllers.
Implement versioning for your API.
Use action filters for cross-cutting concerns.
Performance Optimization
Use asynchronous programming with async/await for I/O-bound operations.
Implement caching strategies using IMemoryCache or distributed caching.
Use efficient LINQ queries and avoid N+1 query problems.
Implement pagination for large data sets.
Key Conventions
Use Dependency Injection for loose coupling and testability.
Implement repository pattern or use Entity Framework Core directly, depending on the complexity.
Use AutoMapper for object-to-object mapping if needed.
Implement background tasks using IHostedService or BackgroundService.
Testing
Write unit tests using xUnit, NUnit, or MSTest.
Use Moq or NSubstitute for mocking dependencies.
Implement integration tests for API endpoints.
Security
Use Authentication and Authorization middleware.
Implement JWT authentication for stateless API authentication.
Use HTTPS and enforce SSL.
Implement proper CORS policies.
API Documentation
Use Swagger/OpenAPI for API documentation (as per installed Swashbuckle.AspNetCore package).
Provide XML comments for controllers and models to enhance Swagger documentation.
Follow the official Microsoft documentation and ASP.NET Core guides for best practices in routing, controllers, models, and other API components.
