需要帮助让 NGen 恢复工作状态
NGen 对我的计算机不满意，我无法找到一种方法来深入了解出了什么问题。
每次启动后，ngen 都会记录以下消息：
.NET 运行时优化服务 (clr_optimization_v2.0.50727_32) - 服务达到瞬时限制 错误。 将关闭。 最后一个错误 从服务管理器返回： 0x8000ffff。
当我尝试在命令行启动优化服务时，我再次记录相同的错误。
我设法启动 ngen 服务并立即暂停队列（通过编写一个两行批处理文件，如下所示：
网络启动 clr_optimization_v2.0.50727_32
ngen 队列暂停
所以现在我尝试通过执行不同状态级别的项目来清除队列，如下所示：
ngenexecutequeueitems 3 /nologo /详细
但结果始终是：
灾难性故障（异常 HRESULT：0x8000FFFF（E_UNEXPECTED））
...我卸载/重新安装了 Visual Studio 2008。 我已经卸载了 SQL Server 2005，并且运行了“系统文件检查器”： sfc /scannow
缺乏想法，希望得到 ngen 专家的帮助。
我如何获取信息，例如 “是什么导致了这些灾难性的失败？” （请注意，/verbose 选项不会增加我发现的信息量。 “等待生成的队列中有哪些文件？” -- 我可以删除其中一些文件，或者将责任归咎于某个特定文件吗...
卸载并重新安装 .net Framework 2.0 并不容易，因为这是 Vista 并且它是操作系统的受保护部分。
更新： 我还尝试了提供的建议
C:\Windows\Microsoft.NET\Framework\v2.0.50727>ngen 执行队列项目 /nologo 灾难性故障（例外情况 HRESULT：0x8000FFFF（E_UNEXPECTED））
NGen is unhappy on my computer, and i can't find a way to get a deep understanding of what is going wrong.
After every startup, ngen logs this message:
.NET Runtime Optimization Service
(clr_optimization_v2.0.50727_32) -
Service reached limit of transient
errors. Will shut down. Last error
returned from Service Manager:
0x8000ffff.
And when i try to start the optimization service at the commandline i get that same error logged again.
I managed to start the ngen service and immediately pause the queue (by writing a two line batch file, like this:
net start
clr_optimization_v2.0.50727_32ngen queue pause
so now i tried clearing out the queue, by executing items at different status levels, like this:
ngen executequeueditems 3 /nologo
/verbose
but the result is always:
Catastrophic failure (Exception from
HRESULT: 0x8000FFFF (E_UNEXPECTED))
...along the way i've uninstalled/re-installed visual studio 2008.
And i've uninstalled SQL server 2005, and i've run the 'system file checker':
sfc /scannow
Running short of ideas, and would love help from an ngen expert.
How do i get info such as
"What's causing these catastrophic failures?"
(note that the /verbose option doesn't increase the amount of info I find out.
"What files are in the queue to be generated?" -- Can I remove some of those files, or pin the blame on a particular file...
Uninstalling and reinstalling the .net framework 2.0 isn't easy, as this is vista and it's a protected part of the operating system.
Update:
i've also tried the advice offered here (and mentioned in the first reply) -- but i just get the same catastrophic failure message.
C:\Windows\Microsoft.NET\Framework\v2.0.50727>ngen
executequeueditems /nologo
Catastrophic failure (Exception from
HRESULT: 0x8000FFFF (E_UNEXPECTED))

我遇到了同样的问题（安装 Asp MVC 1.0）。
在寻找答案时，我发现了黑客博客，其中一些原因已得到解释。
花了 2 个小时试图解决这个问题，我非常沮丧，因为我使用了

也许这会有所帮助..
