为什么System.Windows.Interactivity不想工作？

Question

我刚刚将这一行添加到我的XAML文件中:

xmlns:interactivity="clr-namespace:System.Windows.Interactivity"

首先,我得到一个未定义的CLR命名空间错误,但在构建之后它被修复了.现在,当我尝试在mt XAML文件中添加交互标记时,我在此命名空间中收到完整错误.

这是我的代码示例

<Window x:Class="ColorTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:interactivity="clr-namespace:System.Windows.Interactivity"
    xmlns:ignore="http://www.ignore.com"
    mc:Ignorable="d ignore"
    Height="576"
    Width="720"
    Title="MVVM Light Application"
    DataContext="{Binding Main, Source={StaticResource Locator}}">

<Grid x:Name="LayoutRoot" Background="#FF44494D">
    <Rectangle x:Name="Color01" Fill="#FFF4F4F5" HorizontalAlignment="Left" Height="100" Margin="10,29,0,0" Stroke="Black" VerticalAlignment="Top" Width="100">
        <!--<interactivity:Interaction.Triggers>
            <interactivity:EventTrigger EventName="MouseDown">
            <interactivity:InvokeCommandAction Command="{Binding MyCommand}"/>
        </interactivity:EventTrigger>
        </interactivity:Interaction.Triggers>-->
    </Rectangle>
  </Grid>

在这里提供帮助是我的项目文件的一部分与我的参考

    <Reference Include="GalaSoft.MvvmLight.Extras.WPF45">
      <HintPath>packages\MvvmLightLibs.4.2.30.0\lib\net45\GalaSoft.MvvmLight.Extras.WPF45.dll</HintPath>
    </Reference>
    <Reference Include="GalaSoft.MvvmLight.WPF45">

    </Reference>
    <Reference Include="Microsoft.Practices.ServiceLocation">

      <HintPath>packages\MvvmLightLibs.4.2.30.0\lib\net45\System.Windows.Interactivity.dll</HintPath>
    </Reference>
    <Reference Include="System.Xml" />
    <Reference Include="Microsoft.CSharp" />
    <Reference Include="System.Core" />
    <Reference Include="System.Xml.Linq" />
    <Reference Include="System.Data.DataSetExtensions" />
    <Reference Include="System.Xaml">
      <RequiredTargetFramework>4.0</RequiredTargetFramework>
    </Reference>
    <Reference Include="WindowsBase" />
    <Reference Include="PresentationCore" />
    <Reference Include="PresentationFramework" />

为了完成,我想告诉你我安装了Blend但从未打开或使用它.

这是XAML中交互性的正确名称空间:

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
