__declspec(dlllexport) for the class in your exe
__declspec(dllimport) for the class in your dll

The difficulty is the mutual dependancy makes linking a pain because the exe
needs the dlls lib and the dll needs the exes lib. Here what you do...

link the exe and it will fail because the import .lib for the dll doesnt exist
but it will create the import lib for the exe anyways
link the dll and it will link properly using the exes import lib and also
generate the  import lib for the dll
link the exe again this time it can succeed because the import lib for the dll
is there.
