WCF:Configure svc MIME type on Vista IIS 7.0

假如输入http://localhost/service.svc，返回error 404.3-Not found and the mime type not being configured correctly to be served。很有可能是因为VS之后安装或修改了IIS，就如同aspnet_regiis.exe一样。

解决方法就是执行以下命令：

C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe -i

What it did, it installed the necessary scriptmaps at the IIS metabase root and folders within.
