我用 C++/CLI 创建了一个 DLL，以便包装一些非托管 C++ 代码（例如 boost）。只要我，这项工作就很好

  • 将所有依赖的 DLL 放在一个文件夹中，然后
  • 通过环境将该文件夹传播%PATH%到 IIS（需要重新启动系统）。

bin但是，Microsoft 声明将所有依赖项放在应用程序路径下的目录中就足够了。这最终会说以下内容：

Server Error in '/' Application.

我已经查看了Microsoft和其他人的建议并进行了相应的调整web.config。他们都不适合我。

   <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <probing privatePath="/bin;bin/modules;/modules;\modules;bin\modules" />
            <dependentAssembly>
                <assemblyIdentity name="boost_chrono-vc100-mt-gd-1_52" publicKeyToken="0" culture="neutral" />
                <codeBase version="0.0.0.0" href="file:///C:/app/bin/modules/boost_chrono-vc100-mt-gd-1_52.dll" />
            </dependentAssembly>
    </assemblyBinding>
   </runtime>

是否有可能告诉 IIS 仅针对此应用程序的特定路径，例如通过web.config. 我认为在生产系统上，通过系统范围提供所有这些库并不是很明智%PATH%。至少找不到哪个DLL会很有趣（我知道依赖walker，但由于所有DLL都在同一个目录中，它不会抱怨任何丢失的文件）。

我想从位于“bin”子文件夹中的 C++ DLL 执行函数，并且在 IIS 上，我必须将我的 Web 应用程序添加到具有 ADMIN 权限的 AppPool。之后，它加载没有错误，在常见的 AppPool 中它不会正确加载（执行）。
