当您引用库时，不仅要将.dll还要复制到TargetDir，还要复制到.config

I have an additional config file for my library. I use it to config log4net. So library can configure log4net. I add reference to the library to another project in my solution and i need to make VS copy not only .dll file, but also .config file. How can i do it? Thanks.I have an additional config file for my library
