                Platform::String^ SayHello();
            };

            private ref class HelloWorldImpl sealed :[Platform::Metadata::RuntimeClassName] IHelloWorld
            {
            public:
                HelloWorldImpl();
                virtual Platform::String^ SayHello();
            };

            Platform::String^ HelloWorldImpl::SayHello()
            {
                return L"Hello World!";
            }
        }
    }
