Using Visual Studio 2010 C++. I have a project which uses MFC and I am statically linking to MFC. I am in the process of trying to extract the non-GUI functionality into a separate static library project. Because I want to use CStrings in my library project (debatable whether I should, but for the sake of argument) I now need to reference MFC in both my library and my exe projects.

My question is if I statically link with MFC in my library project and in my exe project, will I effectively have two copies of MFC linked in my final exe? What if I added a third project so I had multiple libraries referencing mfc? That sounds bad but I'm not sure how to get around it.

You don't need to link a library project, so there won't be an extra copy of MFC being linked in. You'll be creating a dependency on the MFC library from your static library, but that's normal. As long as the .exe project includes both libraries, everything will come out all right in the end.
