发布Silverlight，报错 <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

在发布silverlight时，报如下错误：

 

 

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error: 

Line 21:       </serviceBehaviors> Line 22:     </behaviors> Line 23:     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> Line 24:   </system.serviceModel> Line 25:     <system.web>

 注意 allowDefinition='MachineToApplication' beyond application level，说明你在IIS上发布的应用程序不符合要求。

重新再IIS中添加虚拟目录，勾选上“执行（如ISAP应用程序或CGI）（E）”选项即可，然后会在IIS默认网站下显示一个齿轮状的文件夹标示，将编译好的silverlight程序拷贝到该文件夹下就不会出现这个错误了。
