In this module, we will delve into the fundamentals of OOP in C# and understand the concept of classes and objects. We will break down the essential pillars of OOP, including abstraction, and demonstrate their role in creating modular code. A recap will consolidate your learning before you move on to the next section.

In this module, we will explore how fields in C# are utilized within classes, distinguishing between constants, static fields, and read-only fields. You will also gain an understanding of the important distinction between value and reference types, enriching your knowledge of memory management. A recap will prepare you for the next learning stage.

In this module, we will dive into methods in C#, exploring how constructors, destructors, and overloading enhance class functionality. You will also learn about encapsulation, one of the core principles of OOP, ensuring the secure handling of data. The section will conclude with a review of key concepts and a preview of the upcoming topics.

In this module, we will examine the concept of interfaces in C#, their implementation, and their role in enhancing the modularity and reusability of code. You will learn about static members and properties within interfaces, along with the reasons why interfaces are crucial in object-oriented programming. A summary will recap the key lessons before moving to the next section.

In this module, we will cover inheritance, one of the pillars of OOP, and its practical implementation in C#. We will also explore key concepts such as constructor behavior in base and derived classes, access modifiers, and why multiple inheritance is not supported in C#. The section will conclude with a recap and a look ahead at the next module.

In this module, we will explore polymorphism, the final pillar of OOP, focusing on method hiding, method overriding, and abstract classes in C#. You will also understand the importance of preventing polymorphism in certain scenarios. The section will end with a brief summary and an introduction to the next topics.
