Why take this course?

Why should you subscribe to this course?

Nowadays, almost all AI technologies’ SDK or API start with Python. Support for C# comes second. Some don’t even support C#. However, we C#ers (pronounced as CSharpers) know that C# is a powerful computing language that can create almost anything. It should be on the top of the list of AI development. As a programming tutor focusing primarily on C#-related technologies, I must contribute my knowledge to help anyone interested in using C# to develop AI-related applications. We don’t need to be forced to switch to Python or other languages to learn AI, C# is just as good as the others. Sometimes, even better, in my own opinion! Therefore, this course focuses on using C# to bring ChatGPT to your applications by interacting with OpenAI’s APIs.

Grow with the giant!

Bring Generative AI (GenAI) functionality, such as ChatGPT, to your application, is not as hard as a couple of years ago. With the emergence of ChatGPT and the APIs provided by OpenAI, we can stand on the giant’s shoulder and grow with the giant. Accessing OpenAI API is all about accessing RESTful web API, and is easier than you might think.

Firstly, you find out what data structure the API you want to connect to expects.

Secondly, you learn the way C# is used to interact with sending and receiving data to and from those APIs.

And finally, you develop a user interface for users to send prompts to those APIs and then display the responses to users.

Pretty easy, right?

I like to make everybody’s life easier by making things easy to understand. The most efficient way to learn new things is not to learn too many “fundamentals” or “theories” at the beginning, but to learn how to build something useful with minimum pieces of knowledge. Then dive deeper later when you have a total picture of what’s going on in your head. This is also how this course is organized.
