使用 WinDbg/SOS 调试托管->本机调用堆栈。我收到“无法请求 ThreadStore”
Managed.exe 中的 MyManagedFunc 调用 unmanagement.dll 中的 MyUnmanagementFunc()。我使用 Win32 在 unmanaged.dll 中生成一个小型转储。设置UnhandledExceptionFilter。我可以在调用堆栈中看到 MyUnmanagedFunc，但在托管端没有任何用处。
我应该能够使用 WinDbg 和 SOS.dll 来查看托管调用，对吗？下面是我的 WinDbg 会话。我做错了什么？

MyManagedFunc in managed.exe calls into MyUnmanagedFunc() in unmanaged.dll. I produce a minidump in unmanaged.dll using Win32. SetUnhandledExceptionFilter. I can see MyUnmanagedFunc in the callstack, but nothing usefull in the managed side.
I'm supposed to be able to use WinDbg and SOS.dll to see the managed calls, right? Below is my WinDbg session. What am I doing wrong?

从您的输出来看，您尚未设置正确的符号路径。使用命令 .symfix 使 WinDbg 使用默认的公共 Microsoft 符号服务器（带有本地缓存）。如果您想在会话输出中获得任何详细信息，则需要这样做。有关设置符号的更多信息，请检查 WinDbg 帮助文件（使用 .hh 从 WinDbg 命令窗口启动它）。
从当前输出来看，线程 da0.1340 上出现了被零除异常。但是，如果没有正确的设置，您的 sos 命令不会产生有用的信息。
Judging from your output you have not set up a proper symbol path. Use the command .symfix to make WinDbg use the default public Microsoft symbol server (with a local cache). This is needed if you want to have any detail in your session output. For further info on setting up symbols please check the WinDbg help file (use .hh to launch it from WinDbg command window).
From the current output it looks like you have a divide-by-zero exception on the thread da0.1340. However, without a proper setup your sos commands yield no useful info.
小型转储类型必须是 MiniDumpWithFullMemory。如果不是那种类型，就没有“ThreadStore”。
The minidump type has to be MiniDumpWithFullMemory. If it's not that type, there's no "ThreadStore".
