从Silverlight调用WCF服务 [英] Calling WCF Service from Silverlight

问题描述

我从silverlight调用了本地托管的wcf服务，但出现以下异常.

Im calling a locally hosted wcf service from silverlight and I get the exception below.

IV创建了一个clientaccesspolicy.xml，它位于我的主机的路由中.

Iv created a clientaccesspolicy.xml, which is situated in the route of my host.

<?xml version="1.0" encoding="utf-8"?>
<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>

尝试制作时发生错误 对URI的请求 " http://localhost:8005/Service1.svc ". 这可能是由于跨域 配置错误.请参阅 内部异常以获取更多详细信息. --->
