终于ok Silverlight和Wcf跨域通信问题

首先发布Wcf到IIS上

在发布的时候 有时候IIS无法识别svc文件 就需要添加

然后就是添加跨域文件

1.clientaccesspolicy.xml

<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from http-request-headers="*">
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>
  </cross-domain-access>
</access-policy>

2.crossdomain.xml

 

<?xml version="1.0"?>
<cross-domain-policy>
  <allow-access-from domain="*" />
</cross-domain-policy>

 

当发生跨域访问时 IIS会自动在根目录下寻找这两个文件：IIS默认跟目录C:\Inetpub\wwwroot直接添加上述两个文件

需要注意是：不是站点根目录 是IIS根目录

[ServiceContract]
   public interface IService1
   {
       [OperationContract]
       string GetData(int value);

       // TODO: Add your service operations here
   }

public string GetData(int value)
       {
           return string.Format("You entered: {0}", value);
       }
