Topics Covered in ASP.NET Web API

RESTful Principles:

Understanding RESTful architecture is fundamental. You'll learn about statelessness, uniform interface, cacheable responses, and layered systems to design efficient, scalable web services.

HTTP Methods:

Familiarize yourself with HTTP verbs such as GET, POST, PUT, and DELETE. Each method serves a specific purpose in managing data within an application.

Routing and Request/Response Handling:

Discover how to configure URL routing and handle HTTP requests. Understanding action methods and parameter binding allows you to create flexible and dynamic endpoints.

Data Access and Entity Framework:

Learn to interact with databases using Entity Framework Core, a popular ORM (Object-Relational Mapper) for .NET. You'll perform CRUD operations and manage complex data models efficiently.

Security and Authentication:

Implement authentication mechanisms like OAuth2, JWT (JSON Web Tokens), and API keys to secure your APIs. Ensure that your web services protect sensitive data and maintain user privacy.

Advantages of Using ASP.NET Web API

Cross-Platform Compatibility:

ASP.NET Web API is cross-platform, running on Windows, Linux, and macOS. This flexibility allows developers to build applications that can reach a global audience without being restricted to a single operating system.
