Course Description

With ASP.NET Core, we can build Web APIs using C#.

With React, we can create modern, flexible web applications.

In this course, we’ll use both tools to build a complete project. We’ll create an application with a database, user system, back end, and UI, putting into practice all the concepts covered throughout the course.

We’ll go step by step through both the front-end development with React and the back-end with ASP.NET Core. You don’t need to have much experience with either technology to take this course. In fact, I’ll teach you the basics as we go.

By the end, we’ll deploy both our React app and ASP.NET Core app to production.

Here are some of the topics we’ll cover:

  • Building Web APIs with ASP.NET Core

  • Working with SQL Server databases using Entity Framework Core

  • Implementing a user system with JSON Web Tokens (JWT)

  • Developing a single-page application (SPA) with React

  • Creating forms in React

  • Using React Hooks and building custom Hooks

  • Making HTTP requests from React to ASP.NET Core using Axios

  • Using third-party components

  • Displaying maps with Leaflet

  • Storing spatial data in the database with NetTopologySuite

  • Allowing users to upload images and saving them either in Azure Storage or locally

By the end of this course, you’ll have the knowledge and skills to tackle real-world development challenges using ASP.NET Core and React.

Amazing, I learn a lot

I am learning how to build up an Api from the most basic pathway to get a better understanding of the inner workings of how they are used.

easy to understand

By Daniel LAURENS on 11/9/2025

Excellent course. All the topics we need to develop a REACT website with an API are taught. That's very useful and gives us the basics needed to develop our own web applications. Sometimes, the explanations are a bit fast. But globally, I highly recommend this course.

I LIKE THIS COURSE

By Ahmad Almasri on 8/12/2025

Good explanation and Azure was very useful. On the other hand TypeScript wasn’t explained, and there wasn’t a deep dive into .NET Core structure code like repository structure. In general, it is a good course, and I hope it will be enhanced in the futur
