Building a REST API

C# REST API with ASP.NET Core handles CRUD with JSON.

Introduction to C# REST API

A REST API (Representational State Transfer Application Programming Interface) allows different systems to communicate over HTTP. In this guide, we'll explore how to create a REST API using C# and ASP.NET Core that performs CRUD (Create, Read, Update, Delete) operations with JSON data.

Setting Up the ASP.NET Core Project

Adding a Controller

Controllers handle HTTP requests. Let's create a ProductsController to manage our products:

Implementing CRUD Operations

Testing the API

Run your API using the command:

You can test your API using tools like Postman or cURL to make HTTP requests and verify that the CRUD operations work as expected.
