Link a C++/CLI library in a CLR console project - c++

Question

I see on a question that it wasn't possible to link a static C++/CLI library, so I generated a dynamic one and try to link it in a C++ CLR console project with no success
I get:
Error 1 error LNK2020: unresolved token (06000001) cBox::.ctor pTest9.obj
I put the dll (Project ->reference->add new reference) set the include files in the project
(include file with no code)
I don't know what to do (I am new with the C++/CLI)
thanks for suggestions/solution
Library Project declared as DLL
#include "stdafx.h"
using namespace System;
ref class cBox
{
public:
cBox() ;
cBox(double lv,double bv,double hv);
double Volume();
private:
double Length;
double Width;
double Height;
};
CODE OF THE LIBRARY :
#include "stdafx.h"
#include "cBox.h"
cBox::cBox()
{
Console::WriteLine(L"No arg constructor called");
Length = 1.0 ;
Width = 1.0 ;
Height = 1.0 ;
}
cBox::cBox(double lv,double bv,double hv)
{
Console::WriteLine(L"Constructor called");
Length = lv;
Width = bv;
Height = hv;
}
double cBox::Volume()
{
return Length*Width*Height;
}
Then in the Console CLR Project I try to link this library, I get its .h file
#include "stdafx.h"
#include "cBox.h"
using namespace System;
int main(array<System::String ^> ^args)
{
Console::WriteLine(L"Test Library:\n");
cBox^ oBox; // handle of type box
oBox = gcnew cBox;
Console::WriteLine(L"Default Box Volume {0}",oBox->Volume());
return 0;
}

You need to make a couple of changes to get this to work. First, you need to make the class public so your application can use it:
public ref class cBox
{
...
And you need to remove the #include "cBox.h" from your console application project; the inclusion is implicit when using managed libraries.
