我有一个.NET .86应用程序。 我正在尝试从 cdb 运行dumpdomain但不断收到错误。
关于这一点有很多问题，我尝试了几种变体：

我尝试使用 x86 调试器：

我们可以看到这是一个 32 位进程，所以你需要 32 位 SOS。 32 位 SOS 仅适用于 32 位 WinDbg。
对于加载扩展，有 2 个命令。一个是.loadby，一个是.load。对于.loadby使用相对路径，对于.load使用完整路径。
对于.loadby，有 5 个选项：
.loadby sos mscorsvr
.loadby sos mscorwks
.loadby sos clr
.loadby sos coreclr
.loadby sos <somethingelse>
其中mscorsvr真的很旧(.NET CLR 1，服务器版本(，mscorwks很旧(.NET CLR 1和2，但仍然存在(，clr今天很常见(.NET CLR 4(，coreclr可能正在增加(UWP和Silverlight(，<somethingelse>很烦人(查看lm并找到看起来相似但附加数字的东西(。
主要问题是，您尝试在尚未加载 .NET 运行时时加载 SOS。等到 .NET 加载完毕，然后命令将起作用。在初始断点上这当然是不可能的。
用
sxe ld clr
sxe ld mscorwks
sxe ld coreclr
g
让应用程序运行，直到 .NET 可用
