Silverlight：WCF在服务器上获取错误但localhost工作正常

我有silverlight应用程序,我收到此错误：

[Async_ExceptionOccurred]
Arguments: 
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.0.61118.00&File=System.dll&Key=Async_ExceptionOccurred INNER >System.ServiceModel.CommunicationException: [CrossDomainError]

我有一个WCF服务,并在浏览器上正常工作.
我在root站点上有如下所示的clientacesspolicy.xml(WCF服务所在的位置)

<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from >
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>

  </cross-domain-access>
</access-policy>

我做错了什么？
有谁能够帮我？

编辑：

在我的localhost工作正常,但在服务器上没有.
提琴手似乎没问题,没有错误.

我错过了一些IIS配置吗？

上面有更多错误信息：

解决方法

我遇到了同样的问题,并按照这篇文章让我的工作： Making a Service Available Across Domain Boundaries.

我不得不做一个如下变化,有人在那篇文章的底部评论过：

<allow-from http-request-headers="*">
