    }
};

YR_INVOKE(Counter::FactoryCreate, &Counter::RemoteVersion);

// C++ code to create and invoke the instance
int main(void) {
    YR::Config conf;
    YR::Init(conf);

    auto cppCls = YR::CppInstanceClass::FactoryCreate("Counter::FactoryCreate");
    auto cppIns = YR::Instance(cppCls).Invoke();
    auto obj = cppIns.CppFunction<std::string>("&Counter::RemoteVersion").Invoke();
