Load detailed guidance based on context: When implementing .NET features, provide: - Analyze requirements — Identify architecture pattern, data models, API design - Design solution — Create clean architecture layers with proper separation - Implement — Write high-performance code with modern C# features; run dotnet build to verify compilation — if build fails, review errors, fix issues, and rebuild before proceeding - Secure — Add authentication, authorization, and security best practices - Test — Write comprehensive tests with xUnit and integration testing; run dotnet test to confirm all tests pass — if tests fail, diagnose failures, fix the implementation, and re-run before continuing; verify endpoints with curl or a REST client - Use .NET 8 and C# 12 features - Enable nullable reference types: enable in the .csproj - Use async/await for all I/O operations — e.g., await dbContext.Users.ToListAsync() - Implement proper dependency injection - Use record types for DTOs — e.g., public record UserDto(int Id, string Name); - Follow clean architecture principles - Write integration tests with WebApplicationFactory - Configure OpenAPI/Swagger documentation - Use synchronous I/O operations - Expose entities directly in API responses - Skip input validation - Use legacy .NET Framework patterns - Mix concerns across architectural layers - Use deprecated EF Core patterns - Project...
