Ok I know this may be a design issue, so I would love to have remarks on that as well.

I have a Visual Studio web application solution. I have three projects as UserInterface, BusinessLogic and DataAccess.

I had to store some user defined settings and I created configSections in the config file.

I access these configSections through classes which inherit from .NET's ConfigurationSection base class.

So in short for every project I had a separate configSection and for that corresponding configSection I had a class in that project inheriting from ConfigurationSection to access the config section settings.

This works all sweet. But the problem arises if there is any setting which I need to use across multiple projects. So If I need to use a setting defined in UserInterface project configSection in, let say, BusinessLogic project I have to actually make a copy of that setting in the BusinessLogic's configSection. This ends up having the same setting copied across multiple configSections.

Isn't this a bit too redundant?
