It's incredibly frustrating the author doesn't actually say "Garbage Collector (GC)" I'm aware but something niggling in the back of my head had me second guessing.
Even worse: they don't explain what the DATAS acronym means. Seems like the author makes too many assumptions about the knowledge base of their reader IMO.
I am guessing he doesn't expect linking from outside. The blog post before this one starts: "In this blog post I’m going to talk about our .NET 8.0 GC feature called DATAS (Dynamic Adaptation To Application Sizes)."
