由于Windows Server 2003站点默认的MIME类型中没有支持silverlight的相关MIME类型，所以需要自己在IIS里添加，需要添加的MIME类型如下：
.xaml
application/xaml+xml
.xap
application/x-silverlight-app
.manifest
application/manifest
.application
application/x-ms-application
.xbap
application/x-ms-xbap
.deploy
application/octet-stream
.xps
application/vnd.ms-xpsdocument
