不能使用隐式链接.dll中的类

我上课有困难 Shape 从shapetester.cpp中的shape.dll(另一个.dll项目)。

//Shape.h

#ifdef SHAPE_EXPORTS
#define SHAPE_API __declspec(dllexport)

class SHAPE_API Shape
{
public:
Shape();
Shape(int sides, int sideLength, int apothem);
~Shape();

int Perimeter();
double Area();
private:
int sides;
int sideLength;
int apothem;
};
#endif

------------------------------------------------------------
//Shape.cpp

#include "stdafx.h"
#include "Shape.h"

Shape::Shape() : sides(0), sideLength(0), apothem(0)
{
}

Shape::Shape(int sides, int sideLength, int apothem) : sides(sides), sideLength(sideLength), apothem(apothem)
{
}

Shape::~Shape()
{
}

double Shape::Area()
{
    //implementation
}

int Shape::Perimeter()
{
    //implementation
}

-----------------------------------------------------------
//ShapeTester.cpp (this is in another DLL project)
#include "stdafx.h"
#include "ShapesTester.h"
#include "Shape.h"

bool ShapesTester::Test()
{
    Shape myShape = Shape(3, 9, 5); // error here; cant resolve symbol Shape

    return myShape.Area() == 67.5;
}

我在预处理器指令中包含了shape_export,我可以获取.dll和.lib
