UWP 动态磁贴未更新

Question

当我尝试更新我的 UWP 主要和/或次要磁贴时，什么也不会发生。

如果我从 Visual Studio 2017 年开始我的 UWP 应用程序，更新功能可以正常工作并更新磁贴。但是，如果我从 VS 2017 制作一个 Windows Store 应用程序，更新功能将不再起作用。

这是我当前的更新函数：

using System;
using System.Diagnostics;
using Windows.Data.Xml.Dom;
using Windows.UI.Notifications;
using Windows.UI.Xaml.Controls;

namespace UpdateTile
{
    public sealed class TileUpdate
    {
        // Function which is call by every background task to update the app tile
        // and each app secondary tile
        // The tile ID could be empty for update the primary tile
        public static void ScheduleUpdate(String data, String tileID)
        {
            #region variables
            TileUpdater tileUpdater = null;
            #endregion

            // Check the tile ID
            if (tileID == "")
            {
                // If tile ID is empty then create a tile updater for the app tile
                tileUpdater = TileUpdateManager.CreateTileUpdaterForApplication();
            }
            else
            {
                tileUpdater = TileUpdateManager.CreateTileUpdaterForSecondaryTile(tileID);
            }

            tileUpdater.EnableNotificationQueue(true);

            tileUpdater.Clear();

            tileUpdater.Update(new TileNotification(new TileXML().WriteXml(data)));
            }
        }
    }
}

这就是我实际为图块创建 XML 的方式：

using System;
using System.Diagnostics;
using SystemInformation;
using Windows.Data.Xml.Dom;
using Windows.UI.Notifications;
using Microsoft.Toolkit.Uwp.Notifications;

namespace UpdateTile
{
    public sealed class TileXML
    {
        // Function to create a xml document for tiles
        // returns a xml document
        public XmlDocument WriteXml(String data)
        {
            #region variables
            String[] result = { "" }; ;
            SystemInfo sysinfo = new SystemInfo();
            TileContent content = null;
            String textCaption = "";
            String textCaptionSubTle1 = "";
            String textCaptionSubTle2 = "";
            String textCaptionSubTle3 = "";
            #endregion

            Debug.WriteLine("Create xml document for tile");

            if (String.IsNullOrEmpty(data))
            {
                // Set xml text for initial text file data
                textCaption = "No data available";
            }
            else
            {
                // Split text file data by carriage return and new line
                result = data.Split(new string[] { "\n", "\r\n" }, StringSplitOptions.RemoveEmptyEntries);

                // check the result length to create an xml document text
                if (result.Length == 1)
                {
                    // Set xml text if no data file exists
                    textCaption = "No data available";
                }
                else
                {
                    // Set xml text if data file is present
                    textCaption = sysinfo.Hostname;
                    textCaptionSubTle1 = result[3].Replace("Enterprise", "") + " v" + result[4];
                    textCaptionSubTle2 = "IP: " + sysinfo.IP_Address;
                    textCaptionSubTle3 = "Hotline: " + result[1];
                }
            }

            // Create an adaptive tile content
            content = new TileContent()
            {
                Visual = new TileVisual()
                {
                    TileWide = new TileBinding()
                    {
                        Content = new TileBindingContentAdaptive()
                        {
                            BackgroundImage = new TileBackgroundImage()
                            {
                                Source = "Assets/Backgroung.png",
                                HintOverlay = 60
                            },

                            Children =
                            {
                                new AdaptiveText()
                                {
                                    Text = textCaption,
                                    HintStyle = AdaptiveTextStyle.Caption
                                },

                                new AdaptiveText()
                                {
                                    Text = textCaptionSubTle1,
                                    HintStyle = AdaptiveTextStyle.CaptionSubtle
                                },

                                new AdaptiveText()
                                {
                                    Text = textCaptionSubTle2,
                                    HintStyle = AdaptiveTextStyle.CaptionSubtle
                                },

                                new AdaptiveText()
                                {
                                    Text = textCaptionSubTle3,
                                    HintStyle = AdaptiveTextStyle.CaptionSubtle
                                }
                            }
                        }
                    }
                }
            };

            // return the xml domument from adaptive tile content
            return content.GetXml();
        }
    }
}

我也尝试过使用 RAW XML 来更新图块，但没有任何效果。有谁知道为什么磁贴更新适用于 VS 2017，但不适用于 Windows 商店应用程序？

问题已自行解决

当我为动态磁贴创建 XML 时，我设置了背景图片：

BackgroundImage = new TileBackgroundImage()
{
    Source = "Assets/Backgroung.png",
    HintOverlay = 60
},

当我将其注释掉并制作一个新的 Windows 商店应用程序时，实时更新将再次运行。

可能图片尺寸不对
