为Windbg获取正确的.net本机符号

问题描述

我正在进行一些故障转储调试，在其中查找从生产服务器获取的转储.我在其上运行WinDbg的计算机必须安装稍有不同的.NET运行时版本-加载.NET系统程序集的本机映像时出现错误(因此无法加载例如System.Data.Linq).

I'm doing some crash dump debugging, where I am looking a dump taken from a production server. The machine I'm running WinDbg on must have a slightly different version of the .NET runtime installed -- I'm getting errors loading the native images of .NET system assemblies (so can't load for example System.Data.Linq).

确保调试机器可以访问所有正确符号的最佳方法是什么?

What is the best way to ensure that my debug machine has access to all the right symbols?

推荐答案

名称中的ni表明这是一个本机版本(已对ngen优化)，因机器而异.您必须在具有ngen的dmp的计算机上创建PDB:

the ni in the name shows that this is a native version (ngen optimized) which differs from machine to machine. You have to create the PDB on the machine where you got the dmp with ngen:

ngen createpdb C:\Windows\assembly\NativeImages_v4.0.30319_32\System.Data.Linq\
f989891b3a507d4aaec44ab1df12e9d5\System.Data.Linq.ni.dll c:\symbols /debug

现在将C:\ symbols中的PDB添加到Windbgs符号路径中.

Now add the PDBs from C:\symbols to Windbgs symbol path.
