In this session, we explore the **`System.Object` class in C#**, its core methods, and essential object-oriented concepts including equality comparison, hashing, cloning, and resource management.
You will gain a clear conceptual understanding of how every type in .NET inherits from `Object`, how equality works, why `GetHashCode()` matters, and how to properly manage resources using `IDisposable`. The session also covers shallow vs deep copy and object relationships in OOP.
