关键词：IE8 VS2005 C# ASP.NET 断点 不能 无法调试 断点失效
解决：（原文）
IE 8 has a feature called Loosely-Coupled Internet Explorer (LCIE) which results in IE running across multiple processes.

Older versions of the Visual Studio Debugger get confused by this and cannot figure out how to attach to the correct process. You can work around this by disabling the process growth feature of LCIE. Here's how:
1) Open RegEdit
2) Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main
3) Add a dword under this key called TabProcGrowth
4) Set TabProcGrowth to 0
简单来说，在“HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main”下添,创建一个DWORD类型键，名称是TabProcGrowth，值为0,再调试就搞定
我是在XP下把IE7升级到IE8，调试ASP.NET /C#程序。
vs2008+ie8调试和断点
Microsoft 发布了更新的 Microsoft Visual Studio 2008 SP1 调试器组件。 主要是解决问题的发生与单步执行和命中断点。
