内存之谜Windows:一些程序集映射了两次或更多次... [英] The mystery of memory WIndows: some assemblies mapped twice or more...

问题描述

我已经注意到使用ProcXP(VMMap)一些ASP.NET应用程序(.NET 4)
将某些程序集加载(或映射?)两次或更多次.

我使用带有AnyCPU选项的VS 2010(W7 x64)，并在2008 R2 x64服​​务器上进行了测试....这两个应用程序均符合发布/调试选项，结果是相同的.

可以使用任何空白"(读取默认)ASP.NET应用程序来构建此"问题".

这里有一些例子:

我发现的东西:
*是重定位的dll(读取重定基)
*图像类型为32位.
*此问题仅在x64系统中可见(在x32世界中不可见).

谁能让我知道或解释为什么程序集被映射两次(或多次)，这是有原因的?

PS

如果需要，我可以提供空白/默认应用程序示例:).
请避免对外来的多态代码或汇编语言进行转基因..

I have noticed using the ProcXP (VMMap) that some ASP.NET applications (.NET 4)
load (or maps?) some assemblies twice or more.

I use VS 2010 (W7 x64), with the AnyCPU option and tested in 2008 R2 x64 server....the apps are both complied with release/debug options, the result it''s the same.

This "problem" can be build with any "blank" (read default) ASP.NET application.

here some examples:

https://www.dropbox.com/s/68hxmgwca97x3x7/img.zip

The things I found:
* are relocated dlls (read rebasing)
* Image Type is 32 bit.
* this problem is visible only in x64 systems (not in x32 world).

Could anyone let me know or explain why the assembly are mapped twice (or more), there is a reason ???

PS

if you need, I can provide the blank/default application sample :).
Please, avoid alien polymorphic code or assembler language genetically modified..
Thx
