工作环境：
Vista Business
IIS7.0
Visual Studio 2008
我的解决方法：
在IIS中的.NET CompilationK中将Default Language改为程序开发语言（我的为C#，不知道怎么设置中变成VB了）
其实方案：
1、重启电脑
2、修复安装microsoft .net framework（参考地址：http://www.vbforums.com/archive/index.php/t-405951.html）
PS:这个问题出现得有点莫名其妙（在VS中生成时有会出现同样的错误），在网上搜索也没有找到解决办法。在检查IIS设置的时候
发现的解决办法。想到网上了没有解决办法（可能遇到这个问题的人太少了）就发上来留个案也供大家参考下。
如果有哪位大侠知其所以然也请告知。
