MSDN features an article covering reasons why and how managed applications can suffer from memory leaks, how you can find them and get rid of them:
Despite what a lot of people believe, it’s easy to introduce memory and resources leaks in .NET applications. The Garbage Collector, or GC for close friends, is not a magician who would completely relieve you from taking care of your memory and resources consumption.
I’ll explain in this article why memory leaks exist in .NET and how to avoid them. Don’t worry, I won’t focus here on the inner workings of the garbage collector and other advanced characteristics of memory and resources management in .NET.
