ASP.NET Core Web API Introduction
ASP.NET Core Web API Introduction
Section titled “ASP.NET Core Web API Introduction”ASP.NET Core Web API is the HTTP API framework in the modern .NET platform. It is used to build backend services, internal APIs, public REST endpoints, and backend-for-frontend layers.
Why Teams Use ASP.NET Core Web API
Section titled “Why Teams Use ASP.NET Core Web API”- strong integration with the wider .NET ecosystem
- built-in dependency injection and configuration
- flexible request pipeline through middleware
- good fit for API security, validation, and production hosting
What You Need To Understand First
Section titled “What You Need To Understand First”An ASP.NET Core Web API application is usually built from a few core pieces:
- endpoints or controllers that define the HTTP surface
- models and DTOs that define request and response contracts
- middleware that shapes cross-cutting behavior
- services that contain business logic
- configuration for authentication, authorization, logging, and hosting
Typical Use Cases
Section titled “Typical Use Cases”- line-of-business APIs for web and mobile apps
- microservice endpoints
- integration APIs between internal systems
- backend services for SPAs or server-rendered apps
Where To Go Next
Section titled “Where To Go Next”- Read Web API Overview for the section map.
- Use Features for the core concept index.
- Continue with Controllers and Routing.
- Then read Middleware and Pipeline.
- Use Entity vs DTO for contract design guidance.
