Silverlight：WCF在服务器上出错，但本地主机正常

Question

我有silverlight应用程序，并且出现此错误：

[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WCF服务，并且可以在浏览器上正常工作。我在根站点（位于WCF服务所在的位置）中具有如下所示的clientacesspolicy.xml。

<?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？有谁能够帮助我？

编辑：

在我的本地主机上工作正常，但在服务器上却没有。提琴手似乎还可以，对此没有任何错误。

我是否缺少某些IIS配置？

我遇到了同样的问题，并按照这篇文章开始工作：使服务跨域边界可用。

我必须做出如下更改，有人在那篇文章的底部评论道：

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