ASP.NET Core Backend API

This project implements a Backend API using ASP.NET Core, following a layered and modular structure, aligned with enterprise standards and cloud-native best practices.

It is designed to expose RESTful APIs, enforce security at the application level, and integrate cleanly with downstream services and infrastructure.

🧭 Responsibilities of This API

  • Expose RESTful HTTP endpoints
  • Handle request validation and response serialization
  • Enforce authentication and authorization
  • Orchestrate application and domain logic
  • Access data through repositories or services
  • Provide API documentation (Swagger/OpenAPI)
  • Emit structured logs and telemetry

🚫 Non-Responsibilities

  • UI rendering or frontend logic
  • Certificate or TLS management
  • Infrastructure provisioning
  • Client-side state management
  • Hardcoded secrets or credentials

The API must remain stateless and focused on application concerns only.

🔐 Security Considerations

  • Authentication is enforced at the API layer (e.g. JWT, OAuth2, Entra ID)
  • Authorization policies are applied at controller or endpoint level
  • Sensitive configuration is injected via environment variables
  • No secrets are stored in source code or configuration files
  • HTTPS and certificates are managed by the hosting platform (e.g. Azure)

🌱 Configuration Strategy

  • Configuration follows the standard ASP.NET Core hierarchy:
  • appsettings.json
  • appsettings.{Environment}.json
  • Environment variables
  • Local development secrets are handled via .env (not committed)
  • Environment-specific behavior must not be hardcoded

(ASP.NET Core Web API)

This structure follows ASP.NET Core conventions, promotes clarity, and supports scalable enterprise APIs.
