Project Description

Simple C# class to help you understand object oriented programming concepts

Object oriented programming. What is it?

That was my biggest question when I started programming.

It took me many months to get the object oriented programming concept fully cemented in my mind. Now I will help you get object orientation in less than an hour. Avoid needlessly complicated explanations that you find on the internet, as I explain everything in PLAIN language.

Object Oriented programming (OOP) is used in almost every popular language out there, be it Java, C#, Javascript or PHP. You’ll also need it for iOS and Android apps if you make those!

When I learnt object oriented programming it was from videos made by boring instructors. I wanted it to be fun and that’s why everything I explain is illustrated using Lego. Lego is the perfect tool because it is exactly like programming – they both are construction tools, used to build a final product.

We will do a little light programming during the course to demonstrate what OOP is. Our language of choice is C# because we can write it in the excellent (and free) cross platform software: Xamarin. Xamarin allows us to learn object oriented programming in C# on PC, Mac or Linux.

You do not need to know any C# (or even basic programming) beforehand.

Course highlights

  • Fundamental object oriented programming concepts are explained
  • A few more advanced ideas are covered too
  • Some homework to get you thinking
  • Fantastic Lego illustrations


What are the requirements?

  • A PC with internet access to set up Xamarin (an open source .Net engine)
  • You can also run Xamarin on a Mac (or Mono-Develop on Linux)


What will you get from this course?

  • 12 carefully sculpted lectures, complete with excellent Lego illustrations!
  • Learn to code by thinking in an Object Oriented manner
  • Make beautiful, concisely written code – the number one asset coveted by anyone looking to hire developers
  • Make a start in professional software development (freelance rates in the USA are $60 - $150 per hour)

Who is the target audience?

  • Anyone that wants to earn a very healthy living writing and creating software
  • People looking to improve their own knowledge of object oriented concepts

Project Assignment

  • Create a simple console project that covers all the aspects of OOP principles. See how few lines you can get all the principles into and post a screenshot for all to see!
