This change exports the class from the DLL. Without this export, the Linker cannot find the class symbol in the object file and I run into a lnk2019 unresolved external symbol __declspec(dllimport) error.

According to microsft documents, __"declspec(dllexport) stores function names in the DLL's export table. When building your DLL, you typically create a header file that contains the function prototypes and/or classes you are exporting and add __declspec(dllexport) to the declarations in the header file. To make your code more readable, define a macro for __declspec(dllexport) and use the macro with each symbol you are exporting:"
