为什么WinDBG找不到mscordacwks.dll？

Question

我正在尝试使用WinDBG来分析我们的一台生产机器的崩溃转储.我的问题的根源似乎是我有一个不同于生产机器的.NET框架版本,只是我不知道如何解决问题.当我转!sym吵闹然后运行!dlk(来自SOSEX)我得到以下错误,因为它试图找到mscordacwks dll

我从生产机器上获取了mscorwks.dll,mscordawks.dll和sos.dll,并将它们放在C:\ mysymbols中.看起来WinDBG正在寻找mscorwks dll中的dll.

Answer 1

Doug Stewart的这个非常完整的解释帮助我解决了这个问题.

摘要:

• 从原始系统获取mscordacwks.dll.
• 将其重命名为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,mscordacwks_x86_x86_2.0.50727.3607.dll针对问题中的特定情况.
• 将该文件复制到目录中windbg.exe.

Answer 2

在这两个命令之后一切都变好了:

0:000> .symfix
0:000> .reload

Answer 3

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可以移动符号的每一种形式，我发现我能得到这个工作的唯一方法是将 mscorwks.dll、mscordawks.dll 和 sos.dll 从生产计算机复制到 C:\WINDOWS\ Microsoft.NET\Framework\v2.0.50727

看来 WinDBG 对于同一 DLL 的多个版本的处理不太好。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。
