I hate the GAC

If a library is in the Global Assembly Cache it is, per C# 4.0 in a Nutshell, going to take precedence over the same library in your bin folder. Confusing! I didn't know this until yesterday, but I've always loathed the GAC because it sort of "hides" dependencies by empowering a false belief that you have everything you need at your app. At least it does for me or anyone else who does not consciously think of the GAC.
