Fresh out the oven, still warm. Top of the tray.
Summary
This article is part 6 of a series on building a .NET garbage collector in C# using NativeAOT. It focuses on implementing the mark phase of garbage collection, explaining how to traverse object graphs to identify live objects by marking reachable objects from roots. The article builds on previous parts that covered GC APIs, memory layout, and reference finding, providing technical implementation details for a mark-and-sweep garbage collector in .NET.

· 5 pulledAfter a long (way too long) break, it's time to resume our journey towards building a .NET garbage collector in C#.
In the previous parts, we saw how to implement the minimal set of GC APIs to allow a simple application to run, and how to lay out the objects in memory to make the heap walkable.
We then learned how to find the references of a given managed object.
If you need a refresher, don't hesitate to...
In the sixth part, we start implementing the mark phase of the garbage collection.
