If you had a DLL that you installed to the GAC that uses the Enterprise
Library, how would you get the Enterprise Library assemblies to access the
primary .config file?

For example… say you take the Enterprise Library… which uses .config files
for all settings.  So when you usually use it, it’s looking for web.config or
app.config.  But… when you have to install your DLL into the GAC, and that
DLL uses the Enterprise Library, which DLL’s may or may not be in the GAC.  
How would, or even IF, the Enterprise Library DLL’s be able to understand and
find the .config?
