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。程序集从相同的位置，在相同的加载上下文中加载。不涉及显式反射 API 或应用程序域。
这不会对具有本机图像 (*.ni.dll) 的本机 DLL 或框架 DLL 进行再现，但对本地构建的程序集以及诸如 System.Threading.Tasks.Dataflow.dll 和 StyleCop.dll 等其他程序集进行再现。
为 x86 编译解决方案时，它不会重现。
我在 Process Explorer 和 VMMap 中看到重复的条目。当我在windbg中中断模块加载时，我在运行x64和x86时看到了不同的行为。
NGENing 组件没有任何区别。
为了演示，我将构建程序集的解决方案和引用该程序集的可执行文件放在一起。我可以提供该代码，但它非常简单：程序集公开一个枚举，EXE 引用该枚举中的一个值并将其打印出来。
当我构建面向 x64 的程序集和 EXE 并运行 EXE 时，我在 VMMap 和 Process Explorer 中看到重复的条目。两者都表明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）。
当我针对 x86 构建完全相同的解决方案并运行 EXE 时，我在 VMMap 和 Process Explorer 中看到程序集的 1 个条目。
我使用“sxe ld TestAssembly”在windbg 下运行了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。
64 位版本中的前 2 个堆栈看起来与 32 位版本中的 2 个相似，但第 3 个堆栈是 64 位独有的。
有什么想法吗？我知道 64bit 是 2x 32bit，但我没想到程序集会被加载两次！:)
我在这里上传了一个重现问题的解决方案：

该 zip 文件中包含重现步骤，但如果有不清楚的地方，请告诉我！
在 64 位中，以下是在 windbg (sxe ld TestAssembly) 下加载程序集时的堆栈：
