需要去微软下载对应asp.NET版本的修补程序
.NET 4 -http://support.microsoft.com/kb/2600088
.NET 2.0
http://support.microsoft.com/kb/2600100 for Win7 SP1/Windows Server 2008 R2 SP1, Windows Vista/Server 2008, Windows XP/Server 2003
http://support.microsoft.com/kb/2608565 for Win7/Windows Server 2008 R2 RTM
仅仅修复单个站点
下载适合版本的ie.browser 拷贝到App_Browsers/文件下 文件下载地址
.NET2.0 推荐使用App_BrowsersUpdate/projects/net40/ie.browser 可以兼容IE10
2.简单介绍App_Browsers文件夹及.browser文件
\App_Browsers文件夹
放置.browser文件(用于标识发出请求的浏览器，并标识这些浏览器具备的功能)。
默认.browser文件列表在C:\windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers中，可全局访问。若要修改定制，只要把相应.browser文件复制到应用程序的\App_Browsers文件夹中修改即可。
.browser文件
浏览器文件,采用XML文件格式如:
<browsers>
<!-- Mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4325) -->
