C++ / CLI Copy Constructor grief

I'm converting another project from Managed Extensions for C++ (.Net 1.1) to C++/CLI (.Net 2+)

In this project we have some copy constructors.

Following http://www.functionx.com/cppcli/classes/Lesson13b.htm I have my copy constructor declared as
Shift(const Shift^ &otherShift);

The code that used to call it is:
Object ^Shift::Clone(){
      return gcnew Shift(*this);
}
But this raises the compile error C3073: 'MyNamespace::Shift' : ref class does not have a user-defined copy constructor.

I've tried (&this), (this), (%this) -- all with varying errors.

So ... how do I call this copy constructor?

Thanks!

Instead of
Shift(const Shift^ &otherShift);
how about
Shift(Shift^ otherShift);


and called with this
Object ^Shift::Clone(){
      return gcnew Shift(this);
}

That compiles ... I think you got it.

Thanks!
