SOLID principles in .NET and C#

SOLID principles are the most fundamental principles of object oriented programming that are absolutely essential to make your code clean, readable and maintainable. In this class, we will go through each of these principles and apply it in C# code in a .NET console application.

What you’ll learn

In this class, you will build an application that reads MD-formatted text from a file, converts it into HTML and saves it into an output HTML file.

We will build our application gradually, applying every one of SOLID principles in turn. We will also add unit tests to our application to demonstrate the benefits of SOLID principles.

Your output application must meet all of the following requirements:

  • Be able to convert text from MD to HTML
  • Comply with Single Responsibility Principle
  • Comply with Open-closed Principle
  • Comply with Liskov Substitution Principle
  • Comply with Interface Segregation Principle
  • Comply with Dependency Inversion Principle

Knowledge of C# fundamentals is required.

Who this course is for

Anybody who wants to be a competent C# programmer.
