Build ASP.NET Core Web API

THIS COURSE HAS BEEN UPDATED TO THE LATEST VERSION [.NET8]

The course is compatible with both versions - .NET7 & .NET8

This is a complete guide to creating ASP.NET Core Web API using .NET8, Entity Framework Core (EF Core), and SQL Server database.

With over 11000 student enrolments and more than 2000 5-star reviews, this course has helped students from all backgrounds to learn and implement ASP.NET core Web API.

This course is for all skill levels and best suits beginners and intermediate developers who have gained knowledge in C# and ASP.NET Web MVC and want to use their skills to learn ASP.NET Core and specifically ASP.NET Core Web API.

In this ASP.NET Core WEB API course, we will use .NET8 and create a REST WEB API.

During this course, you will gain so much experience creating ASP.NET Core APIs and endpoints and by the end, I am confident that you will gain enough practical knowledge to create your own ASP.NET Web APIs.

We will create a very engaging Web API in which we will create the regions and walks of New Zealand and we will create an ASP.NET Core Web API so that clients of this API can consume this data.

We will start with learning what are the principles of REST and understand the files that ASP.NET Core creates as part of a new project.

Then we will create and understand our domain and domain models.

Then we will go ahead and install Entity Framework Core and using EF Core migrations we will create our SQL Server Database.

We will then create controllers for our API and test them using Swagger UI.

We will also understand and implement the concepts of Domain and Data models and use clean coding techniques to build our ASP.NET CORE Web API.

We will use a famous third-party library called Automapper to map objects inside our API.

With all of this, we will go on and create CRUD operations for our Web API. We will perform Create, Read, Update, and Delete operations on our API using the Repository Pattern in ASP.NET Core API.

Then we will understand and implement Authentication and Authorization in ASP.NET CORE Web APIS using JWT tokens and see how we can generate JWT tokens using our API (Server) so that we can Authenticate and Authorize the clients of our application.

We will learn more advanced level stuff by implementing Filtering, Sorting, and Pagination in our ASP.NET Core Web API.

We will use Postman and Swagger to test our Authentication and Authorization.

We will also use ASP.NET Core Identity in our API where we Register users and assign roles to them.
