为什么 WinDBG 找不到 mscordacwks.dll？
我正在尝试使用 WinDBG 分析我们一台生产计算机的故障转储。我的问题的根源似乎是我的 .NET 框架构建与生产机器不同，只是我不知道如何解决问题。当我打开 !sym 噪音然后运行 !dlk(来自 SOSEX) 时，我收到以下错误，因为它试图查找 mscordacwks dll

我从生产计算机中获取了 mscorwks.dll、mscordawks.dll 和 sos.dll 并将它们放入C:\mysymbols.txt看起来 WinDBG 正在寻找 mscorwks dll 内的 dll。
I'm trying to use WinDBG to analyze a crash dump from one of our production machines. The root of my problem seems to be that I have a different build of the .NET framework than the production machine, only I don't know how to fix the problem. When I turn !sym noisy and then run !dlk(from SOSEX) I get the following error as it tries to find the mscordacwks dll

I took the mscorwks.dll, mscordawks.dll and sos.dll from the production machine and placed them in C:\mysymbols. It looks like WinDBG is looking for a dll INSIDE the mscorwks dll.

这个非常完整的Doug Stewart 的解释在这种情况下帮助了我。
摘要：
mscordacwks_AAA_AAA_2.0.50727.xxxx.dll（取决于您的体系结构和特定框架版本） - 例如针对特定情况的mscordacwks_x86_x86_2.0.50727.3607.dll在问题中。windbg.exe目录中。This very complete explanation by Doug Stewart helped me in this situation.
Summary:
mscordacwks_AAA_AAA_2.0.50727.xxxx.dll(depending on your architecture and the specific framework version) - e.g.mscordacwks_x86_x86_2.0.50727.3607.dllfor the specific case in the question.windbg.exe.执行这 2 个命令后，一切都正常：
After this 2 commands everything become OK:
我还发现，使用 64 位版本的 Windbg 并调试“任何 CPU”托管代码项目（其中构建设置为“首选 32 位”）将导致此错误。
I've also found that using the 64bit version of windbg and debugging a "Any CPU" managed code project where the build is set to "prefer 32 bit" will cause this error.
查看此处的文章后 http://codenasarre.wordpress.com /2011/06/22/sending-an-sos/
然后基本上尝试了我能做到的每一种移动符号的化身，我发现我能得到这个工作的唯一方法是将 mscorwks.dll、mscordacwks.dll 和 sos.dll 从生产计算机复制到 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
似乎 WinDBG 不能很好地处理同一 DLL 的多个版本。也许我做错了什么，但将 dll 直接复制到 .NET Framework 目录至少让我启动并运行。
After checking out the article here http://codenasarre.wordpress.com/2011/06/22/sending-an-sos/
And then basically trying every incarnation of moving symbols around that I could, I found that the only way I could get this working was to copy the mscorwks.dll, mscordacwks.dll and sos.dll from the production machine into C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
It seems that WinDBG doesn't do so well with multiple version of the same DLL. Maybe I did something wrong, but copying the dlls directly to the .NET Framework directory at least got me up and running.
除了 CodeFox 的答案之外，您还需要将 mscorwks.dll（或 clr.dll，如果您使用的是 .NET 4+）所在的目录放入 WinDbg 中的图像文件路径（位于“文件”菜单中）。
In addition to CodeFox's answer, you need to put the directory where the mscorwks.dll (or clr.dll if you're using .NET 4+) into the Image File Path in WinDbg (off of the File menu).
