程序集在64位应用程序中加载两次

标签: .net clr

在x64应用程序中,看起来某些程序集被映射到进程地址空间两次。程序集在相同的负载上下文中从同一位置加载。没有明确的反映API或应用域。

这不会对具有本机映像(* .ni.dll)的本机DLL或框架DLL进行repro,但会对本地构建的程序集进行repro,而对其他程序如System.Threading.Tasks.Dataflow.dll和StyleCop进行repro的.dll。

在为x86编译解决方案时,它不会重现。

我在Process Explorer和VMMap中看到了重复的条目。当我在windbg中打破模块负载时,我在运行x64 vs x86时会看到不同的行为。

NGENing程序集没有任何区别。

为了演示,我整理了一个构建程序集和引用该程序集的可执行文件的解决方案。我可以提供该代码,但它很简单:程序集公开枚举,EXE引用该枚举中的值并将其打印出来。

当我构建程序集和EXE目标x64并运行EXE时,我在VMMap和Process Explorer中看到重复的条目。两者都显示引用的程序集位于同一路径。  VMMap显示两个条目的.rsrc,.text和Header部分(以及每个条目中的3个保留块)。

当我构建针对x86的完全相同的解决方案并运行EXE时,我在VMMap和Process Explorer中看到了1个程序集。

我使用“sxe ld TestAssembly”在windbg下运行32位和64位版本,以观察有问题的程序集的负载。

在下面的堆栈中,您会看到64位版本中有3个中断,而32位版本中只有2个中断。

64位版本中的前2个堆栈看起来类似于32位版本中的2个堆栈,但第3个堆栈是64位独有的。

有什么想法在这里发生了什么?我知道64位是2x 32位,但我没想到装配会被加载两次! :)

我已经上传了一个解决问题的解决方案:

该zip文件中包含repro步骤,但如果不清楚,请告诉我们!

在64位中,这是在windbg(sxe ld TestAssembly)下加载程序集时的堆栈:
