Object-Oriented Programming in C# for Beginners

Transition from writing simple scripts to designing robust, reusable software systems. Object-oriented programming is the industry-standard paradigm for modern application development, and C# is one of the most powerful and widely used languages to implement it. This course guides you step-by-step through the core concepts of software design, helping you write cleaner, more efficient, and highly maintainable code. You will start by mastering foundational concepts like classes, objects, and constructors before diving into advanced patterns that professional developers use every day. Along the way, you will explore modern C# features such as record types for immutable data and nullable reference types to write safer, crash-resistant code. What you'll learn: - Understand foundational OOP pillars including encapsulation, inheritance, polymorphism, and abstraction - Create and configure custom classes, properties, and methods in C# - Apply modern C# features like record types, pattern matching, and nullable reference types - Implement interfaces and abstract classes to build flexible and decoupled systems - Practice writing clean code that follows standard object-oriented design principles This text-based course is designed for beginners with a basic grasp of programming variables and loops who want to transition to professional software design. There are no advanced prerequisites, as every concept starts with clear terminology and step-by-step explanations.
