我为 Visual Studio 2013 编写了一个扩展。由于该死的 ComboBox 错误，我不得不将 System.Windows.Interactivity 包含到我的项目中。 要添加更多详细信息：
效果：当包含提到的ComboBox的编辑器部分显示时，我立即收到异常：
PresentationFramework.dll 中发生了“System.Windows.Markup.XamlParseException”类型的第一次机会异常
附加信息：无法加载文件或程序集“System.Windows.Interactivity，PublicKeyToken=31bf3856ad364e35”或其依赖项之一。 该系统找不到指定的文件。
我在实验实例和文件夹中运行扩展：
C:\Users\<user>\AppData\Local\Microsoft\VisualStudio\12.0Exp\Extensions\<Company>\<Extension>\1.0
包含 System.Windows.Interactivity.dll，但出于某种原因，IDE 似乎看不到它。
更奇怪的是，我正在使用其他附加软件包，例如 IronPython，它们从未给我带来过这样的麻烦。
我该如何解决？
实际上， InnerException 包含名为FusionLog字段，其中包含以下内容：

但还有更多。 我使用 ProcMon 来检查，Visual Studio 在哪里查找该 DLL 并最终注意到：
08:46:46,7508050 devenv.exe 7544 CreateFile C:\\Users\\<user>\\AppData\\Local\\Microsoft\\VisualStudio\\12.0Exp\\Extensions\\<Company>\\<Extension>\\1.0\\Lib\\System.Windows.Interactivity NAME NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a 08:46:46,7509231 devenv.exe 7544 CreateFile C:\\Users\\<user>\\AppData\\Local\\Microsoft\\VisualStudio\\12.0Exp\\Extensions\\<Company>\\<Extension>\\1.0\\Lib\\System.Windows.Interactivity.EXE NAME NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a 08:46:46,7510379 devenv.exe 7544 CreateFile C:\\Users\\<user>\\AppData\\Local\\Microsoft\\VisualStudio\\12.0Exp\\Extensions\\<Company>\\<Extension>\\1.0\\Lib\\System.Windows.Interactivity.DLL NAME NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a
Lib 文件夹包含我正在使用的一些 Python 模块（出于脚本目的，因为我使用的是 IronPython）。 而且，具有讽刺意味的是，大会在
C:\\Users\\<user>\\AppData\\Local\\Microsoft\\VisualStudio\\12.0Exp\\Extensions\\<Company>\\<Extension>\\1.0\\文件夹（不含 Lib）。 但是 Visual Studio 在搜索中忽略了它，尽管它是最自然的搜索位置（因为请求程序集也驻留在那里）
这是此问题的解决方法。 我不喜欢它，但它有效:)
解决方案是从源代码强制加载程序集，这样 PresentationFramework 就不必在解析 XAML 文件期间寻找它。 例如：
private static void LoadSystemWindowsInteractivity()
{
// HACK: Force load System.Windows.Interactivity.dll from plugin's
// directory
typeof(System.Windows.Interactivity.Behavior).ToString();
}
static MyEditorFactory()
{
LoadSystemWindowsInteractivity();
}
我有同样的问题。 下面的解决方案对我有用。
[$RootKey$\\BindingPaths{some_guid}]
"$PackageFolder$"=""
<Asset Type="Microsoft.VisualStudio.VsPackage" d:Source="File" Path="MyDef.pkgdef" />
使用Microsoft.Xaml.Behaviors.Wpf而不是System.Windows.Interactivity问题消失了。
以下是迁移方法： https : //devblogs.microsoft.com/dotnet/open-sourcing-xaml-behaviors-for-wpf/ （基本上：安装nuget ，替换 xaml 文件中的 xmlns 命名空间。）
