I have a class library with a app.config file with 4 settings in it. Previously when I tried this (VS2008) as soon as I referenced the library I would not be able to access the config file/application would break, but for some reason it works now. I have referenced the library in 3 applications and I can still access the settings fine but the actual config file is missing. 

Does the config file get compiled along with the library as soon as you reference it or what happens to it?
