Instead of building your application by statically linking to the MFC object-code libraries, you can build your application to use one of the AFXDLL libraries, which contain MFC in a DLL that multiple running applications can share. For a table of AFXDLL names, see DLLs: Naming Conventions.
By default, the MFC Application Wizard creates an AFXDLL project. To use static linking of MFC code instead, set the Use MFC in a static library option in the MFC Application Wizard. Static linking is not available in the Standard Edition of Visual C++.
