使用NHUnspell NuGet包时无法加载文件或程序集Hunspellx64.dll

我有一个ASP.NET/MVC Web角色正在使用NHUnspell NuGet包。当我尝试运行它时，我得到以下错误消息：

Could not load file or assembly 'Hunspellx64.dll' or one of its dependencies. The module was expected to contain an assembly manifest.

这很奇怪，因为据我所知，我的Web角色项目根本不应该尝试加载非托管的Hunspellx64.dll。这应该由托管的NHUnspell DLL来处理。作为构建步骤，该DLL被复制到Web角色的/bin目录中。

更新：感谢Thomas关于WebActivator过时的评论，我得以解决这个问题。我正在复制我对他接受的答案的回复评论，以确保其他有这个问题的人看到解决方案：

在这个错误开始之前，我让NHUnspell成功工作正在发生。坏东西是安装AttributeRoutingNuGet。AttributeRouting拖动旧版本的WebActivator（1.0.0.0）。不幸的是，NuGet不建议在执行更新操作。您必须手动进行更新按照本网页的说明通过Package Manager控制台：

http://www.nuget.org/packages/WebActivator

以下是收到修复之前原始帖子的其余部分：

我已经在我的项目中搜索了对Hunspellx64.dll的直接引用/链接，包括我的NuGet包配置、packages.config、web.config、我的引用列表、原始项目文件等。我找不到对该dll的任何直接引用。我还可以在哪里查找，或者我还可以尝试什么来阻止我的项目直接加载该非托管DLL？以下是ASP.NET错误转储：
