【问题描述】：
由于某种原因，一旦加载 psscor4，我就无法运行任何命令。我已经从 MS 网站下载了 x64 的 psscor4 并将其放在 windbg 所在的同一文件夹中。在加载 psscor4 之前，我可以正常运行 sos 命令，没有任何问题。

The garbage collector data structures are not in a valid state for traversal.
It is either in the "plan phase," where objects are being moved around, or
we are at the initialization or shutdown of the gc heap. Commands related to
displaying, finding or traversing objects as well as gc heap segments may not
work properly. !dumpheap and !verifyheap may incorrectly complain of heap
consistency errors.
Error requesting GC Heap data

我可以在添加 sos 前缀之后运行这些命令。所以 !sos.do 工作正常。但问题是我也无法运行任何 psscor4 特定命令。知道有什么问题吗？我认为 psscor4 输出的错误具有误导性，因为当我将 windbg 附加到此进程时，我认为不会发生任何 GC。
编辑 下面是用于 .NET 4.0 的配置。那么其中哪一个可以与 psscor4 一起使用？

查看我的更新答案：由于 .NET 4.5 是 .NET 4 的就地更新，因此将目标框架设置为 4.0 无济于事。这取决于运行您的应用程序的 PC 上实际安装的 .NET 版本。
