Question

我使用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

，这项工作就很好了

将所有相关DLL放入一个文件夹中
通过%PATH%环境将该文件夹传播到IIS（需要重新启动系统）。

但Microsoft指出，将所有依赖项放在应用程序路径下的bin目录中应该足够了。最后说出以下内容：

Server Error in '/' Application.

Could not load file or assembly 'NETLibd.DLL' or one of its dependencies. The specified module could not be found.

我查看了Microsoft和others的建议，并相应地调整了web.config。他们都没有为我做好准备。

   <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%PATH%系统范围内提供所有这些库是不明智的。至少有趣的是找不到哪个DLL（我知道依赖walker，但由于所有DLL都在同一个目录中，所以不会抱怨任何丢失的文件）。

Answer 1

我想从C ++ DLL执行函数，该函数驻留在＆＃39; bin＆＃39;的子文件夹中，在IIS上我必须使用ADMIN权限将我的Web应用程序添加到AppPool。之后，它加载没有错误，在普通的AppPool中它不会正确加载（执行）。

IIS无法加载依赖DLL
