I keep a GC folder in my Favorites full of links to articles and blog posts about the .NET GC. I thought it would be a good idea to consolidate them all into one blog post, for handy reference. These are the articles I most often post as answers to questions on public newsgroups. If you know of any other good ones, please post them in the comments! If you find some totally erroneous articles, point them out too.
