Using a dll.config file for a dll in the GAC

Is it correct that mydll.dll which is located in the GAC will read mydll.dll.config from the the same path that it is effectiv开发者_运维百科ely called from? As an example, if myprogram.exe runs in c:\test, all I need do is copy mydll.dll.config into c:\test and all will work OK?

In replies to a similar question, mention is made of setting the location of the config file via code using AppDomainSetup.ConfigurationFile. Given the dll is not a standalone executable, it doesn't have a load event or an entry point so where are you supposed to enter that code. I to presume that I can/must create a public static method that sets the location and that method must be called by my executable before actually using the dll?
