ASP.NET Core Web API is a framework for building RESTful web services. It allows us to expose data and business logic to the web using HTTP. In this article, we will learn how to:
Create a web API project
Add model classes and a database context
Scaffold a controller with CRUD methods
Configure routing and URL paths
Call the web API from a client
Add authentication and authorization
Deploy the API
Creating the Project
We can create a Web API project in ASP.NET Core using any of these options:
Visual Studio
Visual Studio Code
Visual Studio for Mac
.NET CLI
For example, using the .NET CLI we can run:
dotnet new webapi -o TodoApi
cd TodoApi
This will create a new Web API project named TodoApi.
Adding Model Classes
We define model classes to represent the data our API will manage. For example, a TodoItem class:
