显示名称为 'System.Windows.Interactivity' 的程序集加载失败

Question

我致力于解决我有多个 WPF 项目的问题。我使用 MVVM 架构，我有一个主应用程序，它从同一解决方案中的其他项目继承用户控件。主应用程序是一个简单的 wpf 应用程序项目，另一个是 class 库。我在 class 库用户控件的初始化组件上收到此错误。该用户控件需要此程序集。我该如何解决这个 problem/error？谁能帮我？谢谢。

Additional information: The assembly with display name 'System.Windows.Interactivity' failed to load in the 'Load' binding context of the AppDomain with ID 1. The cause of the failure was: System.IO.FileLoadException: Could not load file or assembly 'System.Windows.Interactivity, Version=4.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    this is the structure:
          MainProject
            ->Model
            ->ViewModel
            ->DLL
              ->System.Windows.Interactivity.dll(I use this reference)
            ->View
              ->ClassLibraryView.xaml
              code:
        <Window x:Class="MainProject.Views.ClassLibraryView"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:userControl="clr-namespace:ClassLibrary.View;assembly=ClassLibrary"              
                Title="main" Height="500" Width="800" MinWidth="600" MinHeight="400">

            <Grid>
                <userControl:ClassLibraryUserControl/>
            </Grid>

        </Controls:MetroWindow>

-------------------------
    ClassLibrary
     ->Model
     ->ViewModel
     ->View
        ->ClassLibraryUserControl.xaml
        code:

在我看来，您使用的 DLL 版本有误。该 DLL 有许多不同的版本。您需要适用于您的 .NET 版本的那个。您指的是 4.5 版本吗？
