Question

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，在浏览器上运行正常。我在root站点上找到了clientacesspolicy.xml，如下所示（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？有人可以帮忙吗？

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？

我遇到了同样的问题，并按照本文开始工作：Making a Service Available Across Domain Boundaries。

我必须按照以下内容进行一项更改：有人在该文章的底部发表了评论：
