Silverlight与自托管WCF使用TCP双工通信
“跨域访问”问题异常信息

未能连接到 net.tcp://localhost:4503/IMyService。连接尝试的持续时间为 00:00:00.3300189。TCP 错误代码 10013: 试图以其访问权限所禁止的方式访问套接字。。原因可能是，试图以跨域的方式访问某服务，而该服务的配置不支持跨域访问。您可能需要与服务的所有者联系，以公开通过 HTTP 的套接字跨域策略，并在允许的套接字端口范围 4502-4534 之内承载该服务。

让客户端能以“http://<<YourNetTcpIPAddress>>:80/clientaccesspolicy.xml”方式访问到跨域访问配置。
