Introduction to Web API
Welcome to the Microsoft .NET Web API tutorial series. This guide will help you understand the fundamentals of building RESTful services with ASP.NET Web API.
What is Web API?
ASP.NET Web API is a framework that makes it easy to build HTTP services that can be accessed from a wide variety of clients, including browsers and mobile devices. It's a lightweight framework that integrates seamlessly with existing ASP.NET features.
Key characteristics of Web API:
- RESTful Services: Designed to build services that adhere to REST (Representational State Transfer) architectural principles.
- HTTP-based: Leverages standard HTTP protocols for communication, making it highly interoperable.
- Cross-Platform: Can be consumed by virtually any client capable of making HTTP requests.
- Flexible Hosting: Can be self-hosted or hosted within IIS.
Why use Web API?
Web API is the preferred choice for building HTTP services in the .NET ecosystem for several reasons:
- Unified Programming Model: Provides a single programming model for building both HTTP services and RESTful applications.
- Extensive Features: Supports features like routing, model binding, validation, and content negotiation out-of-the-box.
- Openness: Doesn't require System.Web.dll, making it more lightweight and suitable for self-hosting.
- Integration: Works well with other ASP.NET features and the broader .NET ecosystem.
Getting Started
This tutorial series will guide you through the essential concepts, starting from setting up your development environment to deploying your first Web API service.
Core Concepts Covered
Throughout this series, we will explore:
