Implementing a simple garbage collector in C# - Part 1

Starting today, we are initiating a series of articles on garbage collection with a progressive approach. Our goal is to systematically reimplement the garbage collector implemented in the .NET framework. This approach aims to translate the theoretical concepts into practical implementation, providing clear illustrations of the associated challenges.

Garbage collection is a process in computer programming and memory management where the system automatically identifies and frees up memory that is no longer in use by the program. The primary purpose of garbage collection is to reclaim memory occupied by objects or data structures that are no longer reachable or referenced by the program, preventing memory leaks and improving the efficiency of memory utilization.

In this series of articles, we will delve into the core principles and advantages of this paradigm. We will systematically and simply implement (in C#) the theoretical concepts that we address, gaining insights into the limitations of each concept. Ultimately, we aim to develop a comprehensive understanding of how garbage collection works in modern programming languages.

The authoritative textbook on this topic is The Garbage Collection Handbook published in 2023. This book encapsulates the wealth of knowledge amassed by researchers and developers in the field of automatic memory management over the past sixty years.

Without further ado and as usual, let's begin with a few prerequisites to correctly understand the underlying concepts. Continue here.
