Mixing managed and standard classes in a static library

[InMune]

Now I'm confused. I started from the very begining again.

1) I created a new blank solution;
2) added a new "Console (.NET)" project called "Console", and a new "Class Library (.NET)" project called "Library";
3) changed the configuration type of the "Library" project form "dynamic library" to "static library";
3) edited "console.cpp" to use the "Class1" class:

#include "stdafx.h"
#include "..\Library\Library.h"
#using <mscorlib.dll>
using namespace System;

int _tmain()
{
Library::Class1* class1 = new Library::Class1;
return 0;
}

4) built the solution and it worked.
5) Then I explicity defined the constructor of Class1 (with the implementation in the .cpp file);
6) I built the solution and I got

LINK : error LNK2020: unresolved token (06000002) Library.Class1::.ctor

Adding "Library.lib" (the file generated when building the "Library" project) to "aditional dependencies" in the "Console" project properties doesn't change the results.
Doubtlessly, I'm missing something. This should be simple. Here I am not mixing managed and standard classes. There is only a single managed class (Class1). Please help me.
