C++ visual studio doesn't build properly

I'm having some serious issues with Visual Studio 2013. I have C++ console project with 2 files: Main.cpp and A.cpp, I'm importing A.cpp with #include "A.cpp" in Main.cpp.

Here is the problem: When I edit A.cpp and run Main.cpp, the changes do not occur. I have to change Main.cpp as well and only then will Visual Studio notice the change and recompile everything properly.

This is extremely annoying when I'm trying to change something in A.cpp, any idea how to fix this?

EDIT:

I have tried renaming A.cpp to A.hpp and include A.hpp from Main.cpp with same result: changes to A.hpp do not occur in build until I change Main.cpp as well. I have tried putting A.hpp to both header files and source files in the solution explorer, still the same results.

Never do #include "A.cpp"! Only h-files (or hpp) should be included with #include. In case you want use in Main.cpp some functions defined in A.cpp I have to create A.h (and do not change A.cpp) with declarations of that functions. Of course, you need add both Main.cpp and A.cpp to project.

NOTE: If you add A.cpp into VS project and leave #include "A.cpp" (not #include "A.h") this will lead to a problem with redefinition of functions from A.cpp.

See simple explanation in C++ forum and other examples
