使用TypedEventHandler时，函数不是C ++ / CX类的成员

Question

我正在使用Visual Studio 2017中来自here的示例代码通过RFCOMM套接字设置蓝牙服务器。 当我使用TypedEventHandler时：

auto listener = ref new StreamSocketListener();
listener->ConnectionReceived += ref new TypedEventHandler
    <StreamSocketListener^, 
    StreamSocketListenerConnectionReceivedEventArgs^>
    (this, &HolographicTestAppMainV2::OnConnectionReceived);

使用OnConnectrionReceived函数：

void HolographicTestAppMainV2::OnConnectionReceived(StreamSocketListener^ 
listener, StreamSocketListenerConnectionReceivedEventArgs^ args)
{
// Stop advertising/listening so that we're only serving one client
_provider->StopAdvertising();
delete listener;
_socket = args->Socket;
....
}

错误信息不断弹出：

  

E2161无效的委托初始值设定项 - 函数不是C ++ / CX类的成员

我通读了delegates的文档，看起来与我写的相同，这让我很困惑。
