Garbage collection is a built-in mechanism in the .NET runtime that automatically reclaims memory occupied by objects that are no longer in use. It aims to free up memory resources, minimize memory leaks, and enhance application performance.

When I was a beginner programmer, I quickly realized the importance of understanding memory management and garbage collection. Understanding these concepts was not just about mastering the language; it was also about building efficient and reliable applications that perform well and avoid memory leaks.

Introduction to Memory Management in C#

Memory management is a crucial aspect of developing efficient and reliable applications. In C#, this responsibility is shared between the programmer and the runtime environment. The .NET runtime uses garbage collection to automatically clean up memory. However, it’s not foolproof, and developers should also understand and use the IDisposable interface to handle unmanaged resources.

Before we continue, did you know that the name “C#” (pronounced as C-sharp) is inspired by musical notation? 🎼 In music, the sharp symbol (♯) is used to indicate that a note should be raised by a half step. Similarly, C# is meant to be a step above the C and C++ programming languages, offering features like garbage collection…
