CrossConnectivity.Current.ConnectivityChanged += HandleConnectivityChanged在Xamarin forms + UWP中不起作用

using Windows.Networking.Connectivity;

// 在UWP项目的App.xaml.cs文件中添加以下代码
protected override void OnLaunched(LaunchActivatedEventArgs e)
{
    NetworkInformation.NetworkStatusChanged += NetworkInformation_NetworkStatusChanged;
}

private void NetworkInformation_NetworkStatusChanged(object sender)
{
    var connectionProfile = NetworkInformation.GetInternetConnectionProfile();
    var isConnected = (connectionProfile != null && connectionProfile.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess);

    // 处理网络连接状态变化的逻辑
    HandleConnectivityChanged(isConnected);
}

private void HandleConnectivityChanged(bool isConnected)
