WatiN Loading the ConnectionString from Wrong Configuration File

Question

I am running my WatiN unit test using NUnit and TestDriven.NET. I have a App.config file in my WatiN test project. The connectionstring points to the test database. For some reason when the IE is launched using WatiN it picks up the configuration string in the web.config of the WebApps project which is pointing to the dev database.

How can I tell WatiN class lib project to pick up the settings from the App.config and not the web.config?
