App.config from "referenced" projects

Just needed some clarity on this

I have a 2 projects - Project A and Project B (class library windows projects)
Project B is referenced in Project A
Both projects has app.config files

Now the problem
A value in appsettings of ProjectB is not accessible using ConfigurationManager.AppSettings. Note that the code that is trying to access this value is writen in a class within project B itself. When I debug, I notice that "ConfigurationManager.AppSettings" returns only the keys from project A.

The reason why I have this is because I wanted my Project B to be independent of project A settings. Project B is used by multiple projects and I wanted the flexibility of the the other projects to have the facility to set some parameters depending on the requirements.

Is there a way to say which config file to be used in such scenarios or am should I be using some other code to access appsetting from project B. Start Free Trial
