C# 连接到BluetoothSocket时，请求的地址在其上下文中无效

我正在尝试在Windows 10中使用蓝牙连接到插座。代码如下所示：

var services = await DeviceInformation.FindAllAsync(RfcommDeviceService.GetDeviceSelector(RfcommServiceId.FromUuid(new Guid("e2645167-6352-4429-b0db-45a36f424ebc"))));
if (services.Count > 0)
{
    // Initialize the target Bluetooth BR device
    var service = await RfcommDeviceService.FromIdAsync(services[0].Id);

    // Check that the service meets this App's minimum requirement
    if (SupportsProtection(service))
    {
        _service = service;
        try
        {
            await _socket.ConnectAsync(_service.ConnectionHostName, _service.ConnectionServiceName);
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }
    }
}

应用程序在

ConnectAsync

方法中失败。异常消息仅表示请求的地址在其上下文中无效

是否已运行此示例？（注意/dev分支）：您已经运行过这个示例了吗？（注意/发展处）：
