React.NET - ReactScriptLoadException

Question

I keep getting the following error within my ASP.NET MVC 5 solution with React.NET Error while loading "~/Scripts/jsx/components/HomeComp.jsx": TypeError: Object doesn't support property or method 'createClass' at Global code (Script Document:6:1) Line: 6 Column:1 when trying to server side render a react component return within my MVC view. I have bundled all the necessary scripts and tried including the following within my web configs along with adding the following refs to my layout view

@using React.Web.Mvc;
@using System.Web.Optimization;
@using System.Web.Optimization.React;

but I keep getting the same error, I'm guessing its got to do with the way I have setup my solution, any help will be much appreciated. I have shared the project via my google drive for a better understanding. https://drive.google.com/drive/folders/1LCIlQRZNGckYKWbT4fwp1XDrW0lHZ8t9?usp=sharing

It sounds like you're trying to use the legacy React.createClass syntax. This is no longer supported by React out-of-the-box. Try using the newer syntax with React.Component instead. See https://reactjs.org/docs/react-component.html for example.

I haven't had time to update the tutorial :( Maybe someone will submit a pull request to update it, otherwise I can do it if/when I get some free time.
