vs2017: 查找资源字典时出错

Vs2017: An Error Occured while finding the resource dictionary

当我尝试引用我的 app.xaml 文件

中的资源字典时出现以下错误
<Application x:Class="DesignerPoc.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:DesignerPoc"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Dashboard.Designer.WPF;Connection/Views/test.xaml"/>
          </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
 </Application.Resources>

错误

An Error occurred while finding the resource dictionary "pack://application:,,,/Dashboard.Designer.WPF;Connection/Views/test.xaml"

如何解决这个问题??

你的Resource File Pack URI错了。

应该是这样的,包括component部分:

pack://application:,,,/Dashboard.Designer.WPF;component/Connection/Views/test.xaml
