Garbage Collection in C# — How .NET Cleans Up After You 🧹

Ever wonder what happens to all those objects you new up in C#? The .NET runtime has a built-in janitor — the Garbage Collector (GC) — that tracks your memory, cleans up unused objects, and keeps your programs running smoothly. It's not a get out of jail free card though. You still need to handle unmanaged resources. Do you know what those are? Did you know the GC has 3 levels of "generations" for organizing its work or about the large object heap?

In this post, I break down:

  • What garbage collection actually is

  • How generations, marking, and compaction work

  • Why .NET uses a managed heap

  • How memory leaks can still happen

  • And practical tips for writing GC-friendly code
