About This Free Course
In this course, we are going to learn Agentic Coding using Codex (also referred to by some as Vibe Coding). Codex is an Agentic Coding Agent that is developed and maintained by OpenAI, the company behind ChatGPT. It is similar to Claude Code, but IMHO a much better and more professional tool ;-)
Agentic Coding in IMHO, the future of Coding, and in the course, I will teach you the following topics:

Set up MCP Servers for extra capabilities

I will be using Microsoft Windows for installing Codex and using C# as the programming Language, but if you are on a Mac or use a different programming language, most of this course is universal knowledge
All code and resources in the course are accessible in the companion GitHub Repository
So enough talk! Let's get into the wonderful world of Codex!

Who Should Take This Course
"Agentic Coding for C# Developers using Codex" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later â this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination â real reviews plus a working 100% OFF code â is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
