当向Windows 10发送烤面包通知但在Action Center中显示的项目显示为灰色时，我遇到问题

Notification Grayed out

我创建了一个Visual Studio解决方案，该解决方案包含一个包含WCF项目的Windows服务，并且在WCF项目中，我创建了一个Toast通知，该通知一直保存在Windows Action Center中。该项目（WCF项目）具有创建快捷方式的功能，该快捷方式将应用程序的ID与我在Windows注册表中使用以下命令注册的相关联

Set-ItemProperty "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Notifications\Settings\MyWCFWinServiceApp" -Name "ShowInActionCenter" -Type Dword -Value "1"

就像一些教程指出的那样，我按如下方式使用ShellHelper类

我创建敬酒通知的类被编码为

using System;
using Windows.Data.Xml.Dom;
using Windows.UI.Notifications;
using Microsoft.Toolkit.Uwp.Notifications;
using Microsoft.QueryStringDotNET;
using System.Windows.Threading;

namespace apns_user_notification_receiver
{
    class ToastNotificationGenerator {
        private const String APP_ID = "MyWinServiceWCFApp";

        public void GenerateNotification(string Title, string Content) {
            XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastImageAndText04);
            XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
            stringElements[0].AppendChild(toastXml.CreateTextNode("Notifications"));
            stringElements[1].AppendChild(toastXml.CreateTextNode(Title));
            stringElements[2].AppendChild(toastXml.CreateTextNode(Content));
            ToastNotification toast = new ToastNotification(toastXml);
            ToastNotificationManager.CreateToastNotifier(APP_ID).Show(toast);
        }

        public void GenerateNotificationUWP() {
            // In a real app, these would be initialized with actual data
            string title = "Andrew sent you a picture";
            string content = "Check this out, Happy Canyon in Utah!";
            int conversationId = 384928;
            // Construct the visuals of the toast
            ToastVisual visual = new ToastVisual()
            {
                BindingGeneric = new ToastBindingGeneric() {
                    Children = {
            new AdaptiveText() {
                Text = title,
                HintStyle = AdaptiveTextStyle.Title
            },
            new AdaptiveText() {
                Text = content,
                HintStyle = AdaptiveTextStyle.Title
            }
            }
                }
            };

            ToastContent toastContent = new ToastContent() {
                Visual = visual,
                // Arguments when the user taps body of toast
                Launch = new QueryString() {
            { "action", "viewConversation" },
            { "conversationId", conversationId.ToString() }
        }.ToString()
            };

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(toastContent.GetContent());
            // And create the toast notification
            var toast = new Windows.UI.Notifications.ToastNotification(doc);
            ToastNotificationManager.CreateToastNotifier(APP_ID).Show(toast);
        }
    }
}

有人知道为什么会这样吗？我怀疑这与通知可以接收到的激活有关。谢谢
