配置自定义绑定（如带有 Windows 身份验证的 tcp 绑定）在 silverlight4 中不起作用

Question

我有以下带有 TCP 绑定和 Windows 身份验证的服务器配置文件：

<customBinding>
        <binding name="NewBindingTcpSecure">
          <security authenticationMode="SecureConversation">
            <secureConversationBootstrap authenticationMode="SspiNegotiated"   />
          </security>

          <binaryMessageEncoding maxSessionSize="1000000">
            <readerQuotas maxDepth="64" maxStringContentLength="131072" maxArrayLength="16384"
              maxBytesPerRead="16384" maxNameTableCharCount="16384" />
          </binaryMessageEncoding>
          <!--<windowsStreamSecurity protectionLevel="None" />-->

          <tcpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"
            portSharingEnabled="true" />
        </binding>

当我使用 Windows 应用程序进行消费时，它可以工作。 但当我使用 silverlight 4 进行消费时，它不起作用。

我在 silverlight 中的客户端绑定如下：

 <bindings>
            <customBinding>
                <binding name="DefaultTcp">
                    <binaryMessageEncoding />
                    <tcpTransport />
                </binding>
            </customBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://localhost:4502/HelloWcf/Service1.svc"
                binding="customBinding" bindingConfiguration="DefaultTcp"
                contract="ServiceReference1.IService1" name="DefaultTcp" />
        </client>

我收到的错误是：

The message could not be processed. This is most likely because the action 'http://tempuri.org/IService1/GetData' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

请您的帮助...

您是否创建了跨域访问策略以允许 tcp 通信？

<?xml version="1.0" encoding ="utf-8"?> 
 <access-policy>   
  <cross-domain-access>     
   <policy>       
   <allow-from>         
   <domain uri="*"/>       
   </allow-from>       
   <grant-to>         
   <socket-resource port="4502-4506" protocol="tcp" />       
   </grant-to>     
   </policy>   
</cross-domain-access> 
</access-policy>

我知道这个线程有点旧，但以防万一有人检查它，有一个答案是值得的 - Silverlight 不支持安全的 TCP 绑定，如此处记录：
