if you reference the AppSettings or ConfigurationSettings namespace from within the dll and try to read a setting from the config file it will use the one that is associated with the appdomin.
so regardless of whether this z.dll is referenced from a winform .exe or a web app, it will use either the app.config or the web.config associated with the applications entry point/launching assembly...unless the config file name is explicitly overriden by manual construction of a new appdomain...etc just remember to throw an exception if you cannot find the appsetting you are looking for, so if you call into the dll from another .exe you are reminded that you need the specific app setting. -----Original Message----- From: Discussion of advanced .NET topics.

Sent: Friday, December 01, 2006 7:51 AM To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Subject: [ADVANCED-DOTNET] Using the app.config file Good morning all, I'm not sure how to best describe this situation, but here goes. I have this application name "X" which calls a dll named "Y" which calls a dll named "Z". All are 2005 .NET built. What I wanted to do was be able to put some configuration values in the app.config that is associated with "X" so that "Z" would be able to read those configurations stored in X.App.Config file. The only way I could see to be able to do that was to first create a app.config file for "Z" then populate it with the values I would need for that dll. I did this so I could compile "Z" with the my.settings.<value> code. I then took the same configuration names and values that I created in "Z" and put them into the application "X" (which is two levels up in the food chain). I thought a dll would always try to read the highest level of app.config(it's parent parent configuration file) if one existed with the values it needs. Apparently that is not true, or I have missed something in the planning of this project. My goal is to have the called dll read it's parent config file. Is this possible?
