It might sound too trival to ask and I do the same thing as suggested in articles, yet it doesn\'t work as expected. Hope someone can point me to the right direction.

Remember that ConfigurationManager uses only one app.config - one that is in startup project.

If you put some app.config to a solution A and make a reference to it from another solution B then if you run B, app.config from A will be ignored.

So for example unit test project should have their own app.config.
