uwp - 来自appx文件夹的午餐uwp toast通知中的问题

Question

我有 WNS 服务的 uwp app toast 通知。我的应用程序在 Visual Studio 中吃午饭时工作正常，但是当我从 appx 文件夹运行应用程序时，没有显示 toast 通知。吐司通知时我没有任何例外。请原谅我的语言不好。

private async void ToastNotification(NotificationModel notificationModel)
    {
        string title = notificationModel.Title;
        string content = notificationModel.Content;
        string image = notificationModel.ImageUrl;
        int conversationId = notificationModel.Id;
        ToastContent toastContent = new ToastContent()
        {
            Visual = new ToastVisual()
            {
                BindingGeneric = new ToastBindingGeneric()
                {
                    Children =
                    {
                        new AdaptiveText()
                        {
                            Text = title
                        },
                        new AdaptiveText()
                        {
                            Text = content
                        },

                        new AdaptiveImage()
                        {
                            Source = await DownloadImageToDisk(image)
                        }
                    },
                    AppLogoOverride = new ToastGenericAppLogo()
                    {
                        Source = await DownloadImageToDisk(notificationModel.IconUrl),
                        HintCrop = ToastGenericAppLogoCrop.Circle
                    }
                }
            },
            Actions = new ToastActionsCustom()
            {
                Buttons =
                {
                    new ToastButton("view", new QueryString()
                    {
                        { "action", "GoToLink" },
                        { "link", notificationModel.LinkAddress }

                    }.ToString())
                }
            },
            ActivationType = ToastActivationType.Background,
            Scenario = ToastScenario.Reminder
        };
        var doc = new XmlDocument();
        doc.LoadXml(toastContent.GetContent());
        var toast = new ToastNotification(doc);
        toast.Failed += (o, args) =>
        {
            var message = args.ErrorCode;
            MessageBox.Show(message.Message);
        };
        DesktopNotificationManagerCompat.CreateToastNotifier().Show(toast);
        _beharaSqlDependency.NotificationIsSent(notificationModel.Id);
    }
