exportable class must be exportable. If not, a compiler warning is generated. Moreover, all accessible members, is also classes must be exportable. This rule permits a dllexport class to inherit from a DllImport class, and a DllImport class to inherit from a dllexport C Lass (though the latter is not recommended). As a rule, everything that's accessible to the DLL's client (according to C + + access rules) should be part of the Exporta Ble interface.
