Windows.UI.Notifications丢失 [英] Windows.UI.Notifications is missing

问题描述

我想从

2. 我尝试重新安装.Net（我使用4.5.2）


3. 已安装Windows 10 SDK


4. 试图与全局导入


5. 已添加

 < PropertyGroup> 
< TargetPlatformVersion> 1.0< / TargetPlatformVersion> 
< / PropertyGroup> 
  

6. 已添加 System.Runtime.dll 参考

示例代码可能对您没有用：

 使用系统； 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.Text; 
使用System.Threading.Tasks; 
使用Microsoft.Toolkit.Uwp.Notifications; 
使用Microsoft.QueryStringDotNET； 
使用Windows.UI.Notifications; 
 
 
命名空间MessagerClient.Notifications {
 class DefaultWindowsNotification {
 
 public static void notificationTest（）{
 string title = Andrew向您发送了照片; 
 string content =检查一下，犹他州的快乐峡谷！; 
 string image = http://blogs.msdn.com/something.jpg; 
 string logo = ms-appdata：////local/Andrew.jpg; 
 ToastVisual visual =新ToastVisual（）{
 
 BindingGeneric =新ToastBindingGeneric（）{
 
儿童= 
 {
新AdaptiveText（） 
 {
 Text = title 
}，
 
 new AdaptiveText（）
 {
 Text = content 
}，
 
新AdaptiveImage（）
 {
源=图片
} 
}，
 
 AppLogoOverride = new ToastGenericAppLogo（）{
来源=徽标，
 HintCrop = ToastGenericAppLogoCrop.Circle 
} 
} 
}; 
 Console.WriteLine（ NOTIFICATION）; 
 //由于Windows.UI库
而不能使用ToastNotificationManager.CreateToastNotifier（）。Show（visual）; 
} 
} 
} 
  

解决方案

要在Winforms应用程序中使用这些UWP合同，就必须与Visual Studio进行激烈的斗争。您使用错误的TargetPlatformVersion立即走错了脚，很难恢复。采取的所有步骤：

使用文本编辑器编辑.csproj文件，记事本即可。插入以下内容：

 < PropertyGroup> 
< TargetPlatformVersion> 10.0.10586< / TargetPlatformVersion> 
< / PropertyGroup> 
  

假设您的计算机上安装了10586 SDK版本。目前，这些版本变化很快。通过在C：\Program Files（x86）\Windows Kits\10\Explorer中进行仔细检查，可以看到该目录中列出了已安装的版本。

打开Winforms项目，使用项目>添加引用> Windows选项卡>勾选 Windows.Data 和 Windows.UI 合同。再次添加引用，并使用浏览选项卡选择System.Runtime。我在C：\Program Files（x86）\参考程序集\Microsoft\Framework\.NETFramework\v4.6.1\Facades中选择了一个。该参考显示带有警告图标，不确定要说什么，但似乎没有任何副作用。

通过拖放按钮进行测试在窗体上，双击以添加Click事件处理程序。最基本的代码：

 使用Windows.UI.Notifications; 
 ... 
 
 private void button1_Click（对象发送者，EventArgs e）{
 var xml = ToastNotificationManager.GetTemplateContent（ToastTemplateType.ToastText01）; 
 var text = xml.GetElementsByTagName（ text）; 
 text [0] .AppendChild（xml.CreateTextNode（ Hello world））; 
 var toast = new ToastNotification（xml）; 
 ToastNotificationManager.CreateToastNotifier（ anythinggoeshere）。Show（toast）; 
} 
  

通过使用不同的ToastTemplateType添加图像或更多行文本来体现。请记住，您的程序只能在Win10机器上运行。

I want to create simple toast notification to action center in windows 10 from this example. But I got problem on Step 2:

using Windows.UI.Notifications;

It`s missing. But I have spent a lot of time to find it and got no result. I really have no idea where I can find or at least download it.

What I tried:

1. After long search I found Windows.UI.dll in C:\Windows\System32 but when I try to add it as reference into project I got this error. Even after I tried to copy it and made this fully accessible nothing changed

2. I tried to reinstall .Net (I`m using 4.5.2)
3. Installed Windows 10 SDK
4. Tried to import with global
5. Added

<PropertyGroup>
      <TargetPlatformVersion>10.0</TargetPlatformVersion>
</PropertyGroup>

6. Added System.Runtime.dll reference

Example code which probably is useless for you:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Toolkit.Uwp.Notifications;
using Microsoft.QueryStringDotNET;
using Windows.UI.Notifications;


namespace MessagerClient.Notifications {
    class DefaultWindowsNotification {

        public static void notificationTest() {
            string title = "Andrew sent you a picture";
            string content = "Check this out, Happy Canyon in Utah!";
            string image = "http://blogs.msdn.com/something.jpg";
            string logo = "ms-appdata:///local/Andrew.jpg";
            ToastVisual visual = new ToastVisual() {

                BindingGeneric = new ToastBindingGeneric() {

                    Children =
                    {
                        new AdaptiveText()
                        {
                            Text = title
                        },

                        new AdaptiveText()
                        {
                            Text = content
                        },

                        new AdaptiveImage()
                        {
                            Source = image
                        }
                    },

                    AppLogoOverride = new ToastGenericAppLogo() {
                        Source = logo,
                        HintCrop = ToastGenericAppLogoCrop.Circle
                    }
                }
            };
            Console.WriteLine("NOTIFICATION");
            //Can`t use because of Windows.UI library
            ToastNotificationManager.CreateToastNotifier().Show(visual);
        }
    }
}

解决方案

You have to fight Visual Studio pretty hard to use these UWP contracts in a Winforms app. You got off on the wrong foot right away with the wrong TargetPlatformVersion, pretty hard to recover from that. Full steps to take:

Edit the .csproj file with a text editor, Notepad will do. Insert this:

  <PropertyGroup>
       <TargetPlatformVersion>10.0.10586</TargetPlatformVersion>
  </PropertyGroup>

Which assumes you have the 10586 SDK version installed on your machine. Current right now, these versions change quickly. Double-check by looking in the C:\Program Files (x86)\Windows Kits\10\Include with Explorer, you see the installed versions listed in that directory.

Open the Winforms project, use Project > Add Reference > Windows tab > tick the Windows.Data and the Windows.UI contract. Add Reference again and use the Browse tab to select System.Runtime. I picked the one in C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\ .NETFramework\v4.6.1\Facades. This reference displays with a warning icon, not sure what it is trying to say but it doesn't appear to have any side-effects.

Test it by dropping a button on the form, double-click to add the Click event handler. The most basic code:

using Windows.UI.Notifications;
...

private void button1_Click(object sender, EventArgs e) {
    var xml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText01);
    var text = xml.GetElementsByTagName("text");
    text[0].AppendChild(xml.CreateTextNode("Hello world"));
    var toast = new ToastNotification(xml);
    ToastNotificationManager.CreateToastNotifier("anythinggoeshere").Show(toast);
}

Embellish by using a different ToastTemplateType to add an image or more lines of text. Do keep in mind that your program can only work on a Win10 machine.
