这几天framework 自动更新
结果造成webservices调用报错:
System.IO.FileNotFoundException: 找不到文件或程序集名称“ygbe1ssc.dll”，或找不到它的一个依赖项。
文件名: “ygbe1ssc.dll”

google 到微软的解决办法：

说是TEMP文件夹权限问题
提供了一个实用的跟踪办法，详见上面的连接：
<system.diagnostics>
<switches>
<add name="XmlSerialization.Compilation" value="4"/>
</switches>
</system.diagnostics>
但是对我们的服务器无效，最后发现是CSC.EXE被破坏的原因
%system%\Microsoft.NET\Framework\v2.0.50727\csc.exe 文件修改日期为今天，大小为0
复制正常文件替换解决问题
不知道有没有类似自动升级造成的情况
或者是我们服务器被病毒破坏了？
