C# 使用NHUnspell NuGet包时无法加载文件或程序集X64.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，会收到以下错误消息：

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处理。该DLL作为构建步骤复制到Web角色的/bin目录

更新：多亏了托马斯关于WebActivator过时的评论，我才得以解决这个问题。我将我的回复意见复制到他接受的答案上，以确保其他有此问题的人看到解决方案：

在这个错误开始之前，我已经让NHUnspell成功地工作了 发生。是什么打破了这一切 努吉。在旧版本的WebActivator中拖动属性 (1.0.0.0). 不幸的是，NuGet不建议在以下情况下对其进行更新： 执行更新操作。您必须手动执行更新 按照本网页的说明，通过Package Manager控制台：

以下是收到修复之前原始帖子的其余部分：

我已经搜索了我的项目，寻找到Hunspellx64.dll的直接引用/链接，包括我的NuGet packages配置、packages.config、web.config、我的引用列表、原始项目文件等。我找不到任何对该dll的直接引用。我还可以在哪里查看或尝试阻止项目直接加载非托管DLL？以下是ASP.NET错误转储：

WebActivator启动方法不处理bin文件夹中的非托管DLL。 正如您在代码文件中看到的：

Start（）方法将所有DLL作为程序集加载，以探测其PreApplicationStartMethodAttribute。对于非托管DLL，此操作失败，因为没有程序集清单

看起来您正在使用分支（dfolwler？）或WebActivator的过时版本，因为当前版本可以通过忽略程序集加载时的所有异常来处理此问题

private static IEnumerable<Assembly> Assemblies
{
    get
    {
        if (_assemblies == null)
        {
            // Cache the list of relevant assemblies, since we need it for both Pre and Post
            _assemblies = new List<Assembly>();
            foreach (var assemblyFile in GetAssemblyFiles())
            {
                try
                {
                    // Ignore assemblies we can't load. They could be native, etc...
                    _assemblies.Add(Assembly.LoadFrom(assemblyFile));
                }
                catch
                {
                }
            }
        }

        return _assemblies;
    }
}

私有静态IEnumerable程序集
{
得到
{
如果（_assemblies==null）
{
//缓存相关程序集的列表，因为我们在Pre和Post中都需要它
_assemblies=新列表（）；
foreach（GetAssemblyFiles（）中的var assemblyFile）
{
尝试
{
//忽略无法加载的程序集。它们可能是本机程序集，等等。。。
_Add（Assembly.LoadFrom（assemblyFile））；
}
抓住
{
}
}
}
返回组件；
}
}

将WebActivator更新至最新版本。

就是这样做的。在这个错误开始发生之前，我已经让NHUnspell成功地工作了。破坏一切的是用NuGet安装AttributeRouting。在旧版本的WebActivator（1.0.0.0）中拖动属性。不幸的是，在执行更新操作时，NuGet不建议对其进行更新。您必须按照此网页的说明，通过Package Manager控制台手动执行更新：WebActivator已被弃用，取而代之的是WebActivatorEx；希望有一些NuGet技巧可以让WebActivatorEx满足WebActivator的依赖性要求，或者每个需要它的人都转向了WebActivatorEx

private static IEnumerable<Assembly> Assemblies
{
    get
    {
        if (_assemblies == null)
        {
            // Cache the list of relevant assemblies, since we need it for both Pre and Post
            _assemblies = new List<Assembly>();
            foreach (var assemblyFile in GetAssemblyFiles())
            {
                try
                {
                    // Ignore assemblies we can't load. They could be native, etc...
                    _assemblies.Add(Assembly.LoadFrom(assemblyFile));
                }
                catch
                {
                }
            }
        }

        return _assemblies;
    }
}
