Calling C# .NET methods from unmanaged C/C++ code

I need to call c# method in native c++. I followed this guide, download it, it's worked, but when I try it on new version of .net I cannot reproduce. The main idea of this code is call c# method in such way: C# .dll -> C++/CLI(managed c++) -> c++

C#

public static class ManagedClass
    {
        public static bool Check()
        {
            return true;
        }
    }

Managed c++

namespace ClassLibrary1 {

    public ref class DoWork
    {
    public: bool CheckCSharp()
    {
        return CSharp::ManagedClass::Check();
    }
    };
}
__declspec(dllexport) bool Check()
{
    ClassLibrary1::DoWork work;
    return work.CheckCSharp();
}

c++

#include "ClassLibrary1.h"
_declspec(dllexport) bool Check();

int main()
{
    std::cout << Check();
    system("pause");
    return 0;
}

It's show error

Error LNK2019 unresolved external symbol "bool __cdecl Check(void)" (?Check@@YA_NXZ) referenced in function _main

1 unresolved externals
