Course Overview

Complete guide to building an app with .Net Core and React

The complete guide to building an app from start to finish using .Net 9.0, React 19 and React Query

***Course has now been re-imagined and re-recorded for .Net 9.0, React 19 and also now includes React Query***

Have you learnt the basics of ASP.NET Core and React? Not sure where to go next? This course should be able to help with that. In this course we learn how to build a multi-project ASP.NET Core solution that is built using Clean Architecture and the CQRS and Mediator pattern that makes our code easy to understand, reason about and extend.

Both ASP.NET Core and React are hot topics and this course will enhance your knowledge of both, simply by building an application from start to finish. In each module we learn something new, whilst incrementally adding features to the application. Building an application is significantly more rewarding than building yet another Todo List from the documentation!

Every line of code is demonstrated and explained and by the end of this course you will have the skills and knowledge to build your own application using the techniques taught in this course.

Here are some of the things you will learn about in this course:

  • Setting up the developer environment

  • Creating a multi-project solution using the the ASP.NET Core WebAPI and the React app using the DotNet CLI and the create-react-app utility.

  • Clean Architecture and the CQRS + Mediator pattern

  • Setting up and configuring ASP.NET Core identity for authentication

  • Using React with Typescript

  • Adding a Client side login and register function to our React application

  • Using React Router

  • Using AutoMapper in ASP.NET Core

  • Building a great looking UI using Semantic UI

  • Adding Photo Upload widget and creating user profile pages

  • Using React Hook Form and Zod to create re-usable form inputs with validation

  • Paging, Sorting and Filtering

  • Using SignalR to enable real time web communication to a chat feature in our app

  • Publishing the application to Azure

  • Many more things as well

Tools you need for this course

In this course all the lessons are demonstrated using Visual Studio Code, a free (and fantastic) cross platform code editor. You can of course use any code editor you like and any Operating system you like... as long as it's Windows, Linux or Mac

Is this course for you?

This course is very practical, about 90%+ of the lessons will involve you coding along with me on this project. If you are the type of person who gets the most out of learning by doing, then this course is definitely for you.

On this course we will build an example social network application that allows users to sign up to events (similar to MeetUp or Facebook), completely from scratch. All we start with is an empty terminal window or command prompt.

All you will need to get started is a computer with your favourite operating system, and a passion for learning how to build an application using ASP.NET Core and React

    Great course. Neil never disappoints. In my opinion, React looks a bit more confusing than Angular or Vue.js. I find its structure messier than the others. Also, the backend differs from the one I am used to in .NET 5 and .NET 6. More abstractions, even though that's the Clean Architecture pattern, I am more into the old Repository and Unit of Work patterns...This new approach using Mediatr gets my head spinning. Highly recommend though.

    I would recommend this course, but only if you have already some React knowledge. This is not for beginners. I come from a asp classic/webforms/php/vanilla js/jquery background. I have long time struggling to learn these single page js frameworks works, and at the same time asking myself why I should learn them. It is frustrating because most tutorials are awful. Then I bought this one, and after some time, I found it equally disappointing, because once you arrive to the front-end section, he never explain what the f-- is that "useState" or "useEffects" weird functions. He only put the example and you must follow. I paused this course, and after a while I found a great tutorial that really helped me out finally to understand what React was all about in a straight manner: " Learn React With This ONE Project" from "Tech with Tim" channel, in Youtube. In only 1 hr 40 minutes, he explains wonderfully the basic concepts of React, in a straight way, and dont deviates with unrelated technologies or details. That moment was when I finally understood the React's "philosophy" and the basics about how it worked. Then I came here to start over from scratch. As I say, is a good course but he has the following flaws, in my opinion: - He waste time explaining things that a person who bought this course should already know (like what is an "accesor modifier" for a property", etc ) Honesty, this course is not from beginners that are starting from scratch, because the author cant waste time explaining all points of all things for the sake of beginners. - He waste time explaining alternative ways of doings things that you aren't use at the end anyway. This makes you waste time and losing focus on important things. I'm right now in the Error Handling section, and he starts explaining one way of doing things and the next lesson saying "this is not ideal so we are going to do otherwise" .... so WHY did you do that in the first place ? This is part of his teaching style, and is very, very annoying because he makes you type for nothing, and it is a waste of time. I have also his Angular course, and in some sections it is the same. Man, go to the straight o the point. As I said, don't try to do I-can-fit-all in my course... - You must wait until he finish the explanation because you don't know when he will undo it, like for example, when he is running Vite, and then he says "I will chose Typescript". There where actually 2 typescripts options: a) typescript (alone) and b) typescript + SWC. Then he continue his gibberish and then says "so I will chose typescript + SWC. Why not ? " ... it its the same thing regarding the previous point. Suddenly he start explaining a way of doing things, you follow him, and then he say "but this is not the standard way so we aren't going to use it" ... and then erase all the typed code .... Whyyyyy you then explained it ? Look man, your course is good but you have to focus in which kind of audience you will address your teachings, you can't make a one-size-fits all. I think this course could last less time if you really focus on important things related to the main subject.
