c# - Visual Studio 扩展找不到所需的程序集

Question

我为 Visual Studio 2013 编写了一个扩展。因为 bloody ComboBox bug ，我必须将 System.Windows.Interactivity 包含到我的项目中。要添加更多详细信息:

1. 使用额外的解决方案程序集，例如 .Editor，其中包含物理编辑器。
2. .Editor 引用 System.Windows.Interactivity
3. 也引用了 System.Windows.Interactivity。事实上，我正在使用 nuget 加载 Expression.Blend.Sdk 包(它与 WPF 4.5 兼容)

效果:当包含提到的ComboBox的部分编辑器显示时，我立即得到一个异常:

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

Additional information: Could not load file or assembly 'System.Windows.Interactivity, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

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，但由于某种原因，IDE 似乎看不到它。

更奇怪的是，我正在使用其他附加包，如 IronPython，它们从来没有给我带来这样的麻烦。

我该如何解决？

实际上，InnerException 包含名为 FusionLog 的字段，其中包含以下内容:

但还有更多。我使用 ProcMon 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 文件夹包含一些我正在使用的 Python 模块(出于脚本目的，因为我正在使用 IronPython)。而且，具有讽刺意味的是，程序集在

C:\Users\<user>\AppData\Local\Microsoft\VisualStudio\12.0Exp\Extensions\<Company>\<Extension>\1.0\

文件夹(没有 Lib)。但是 Visual Studio 在搜索中忽略了它，尽管事实上它是最自然的搜索位置(因为请求程序集也驻留在那里)

Answer 1

这是解决此问题的方法。我不喜欢它，但它有效:)

解决方案是从源代码中强制加载程序集，这样 PresentationFramework 就不必在解析 XAML 文件时寻找它。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();
}
