Covariant delegates in C++/CLI?

Sorry I can't find anything concrete in respect of this:

I want a delegate to refer to a method that utilises a covariant return
type. I believe this is now legal in .NET 2.0 for C# - what about C++/CLI?

Thanks

Kevin

ref class Mammals
{
};

ref class Dogs : public Mammals
{
};

ref class Program
{
public:
delegate Mammals^ HandlerMethod( );

static Mammals^ FirstHandler( )
{
return nullptr;
}

static Dogs^ SecondHandler( )
{
return nullptr;
}
};

int main( )
{
Program::HandlerMethod^ handler1 = gcnew Program::HandlerMethod(
Program::FirstHandler );

// Covariance should allow this delegate.
Program::HandlerMethod^ handler2 = gcnew Program::HandlerMethod(
Program::SecondHandler );
}
