How can we use a native object inside a managed class

Question

Hi,

I have a c++/cx class with a native object as a private member, how can I use it from a method :

public ref class ZipArchiveEntry sealed :  IArchiveEntry
{
private:
	libzippp::ZipEntry  _native;
        virtual IAsyncOperation<IRandomAccessStream^>^ LoadAsync();
};

/*virtual*/ IAsyncOperation<IRandomAccessStream^>^ ZipArchiveEntry::LoadAsync()
{
	return create_async([this]() -> IRandomAccessStream^
	{
           // How can I access _native member variable?
	});
}

Instead of an object stored on the stack, should I use some kind of std::shared_ptr ? In this case will I be able to access
the member variable ?
