Linker Tools Error LNK2039
importing ref class '<type>' that is defined in another.obj; it should be either imported or defined, but not both
The ref class '<type>' is imported in the specified .obj file but is also defined in another .obj file. This condition can cause runtime failure or other unexpected behavior.
To correct this error
Check whether 'type' must be defined in the other .obj file and check whether it must be imported from the .winmd file.
Remove either the definition or the import.
