Question

我正在开发一个使用gRPC库的ASP.NET Wep API应用程序。在Windows上它工作正常，但如果它在带有Apache和mod_mono的Linux上运行，我会得到以下异常：

- ChangeConfigurationAsync(): gRPC call failed with exception=[System.IO.FileNotFoundException: Message="Error loading native library. Not found in any of the possible locations: /tmp/apache-temp-aspnet-0/17ae072c/assembly/shadow/bc23f1e5/69f27fa4_d5d18e41_00000001/libgrpc_csharp_ext.x64.so,

libgrpc_csharp_ext.x64.so与其他托管DLL放在同一个“bin”目录中，但遗憾的是.so文件未复制到卷影副本目录。

是否可以在mod_mono / Apache上禁用卷影副本？
是否可以在Apache / mod_mono中配置哪些文件应该被阴影复制到哪个目录？

据我所知，gRPC库无法配置为在其他目录中查找非托管库。我们的其他单声道守护进程也没有问题，通常使用gRPC以“mono xy.exe”开头。

我们正在使用：

Mono Ver：5.0.1.1
的Apache / 2.4.6
CentOS 7
gRPC 1.2

您可以尝试设置shadowCopyBinAssemblies =＆＃34; false＆＃34;在你的Web.config中：

<system.web>
    <hostingEnvironment shadowCopyBinAssemblies="false"/>
</system.web>

旧的MSDN文档（没有在docs.microsoft.com上找到它）： https://msdn.microsoft.com/en-us/library/ms228159(v=vs.100).aspx

无法在CentOS 7
