Question

    &l         


        

Answer 1

As others have said, the library will use the config file for the executing application.

I'd like to add one suggestion though. One option to consider, for (in my opinion) a bit of polish and a professional touch is creating a custom configuration section. That would allow you to group the settings for your library and not leave any confusion about which settings are used by your library: http://msdn.microsoft.com/en-us/library/2tw134k3(v=vs.100).aspx
