app.config files of referenced dlls

I have a Web Project (VS 2008) that references a bunch of DLLs. The DLLs are built separately, so the project references binaries and not DLL projects. S开发者_StackOverflow中文版ome of the DLLs have their own app.config, which I want to be copied autmatically to the web project's output directory. Is there any suitable generic way to achieve this?

You should avoid having an app.config for class library projects. You will need to manually merge the values with those of web.config as this would be used by the web project.
