My WCF service works fine with Security Mode="Transport" and clientCredentialType="Windows" (with client and service on either one machine or two). But I need to put the service on the other side of a firewall where Windows Authentication is not possible. I know I can either install X.509 certs or use security="None" (to which I would add my own security protocol). But I cannot get "None" to work! I keep getting 'The socket connection was aborted' error.

Here is the config, please let me know if you spot anything. I have tried it without the 2 lines that specify clientCredentialType="none" but it makes no diff. P.S. Each time I make a config change I stop and restart both the client and the service.

SERVER CONFIG

<system.serviceModel>  
<services>  
  <service name="OuterService.OutCardTrx">  
      <endpoint address="" binding="netTcpBinding" contract="OuterService.IOutCardTrx">

  </service>

不是 100% 确定这是原因，但是您的绑定安全设置在客户端和服务之间不匹配。

请注意，NetTcpBinding 的默认安全性是Transport（对于模式）。您在服务配置中的绑定中定义None，但该绑定从未分配给服务端点，因此您的服务使用 NetTcp 的默认设置。

另一方面，您正在客户端上设置绑定配置。

尝试在您的服务端点中设置绑定配置，如下所示：

<endpoint address="" binding="netTcpBinding" 
          bindingConfiguration="netTcpBinding"
          contract="OuterService.IOutCardTrx">

这会将您指定的绑定分配给端点，并将安全设置为“无”。我还建议将绑定配置名称更改为“netTcpBinding”以外的名称，以避免任何可能的混淆。

您是否尝试在客户端/服务器配置中增加 MaxItemsInObjectGraph、MaxReceivedMessageSize、MaxBufferPoolSize、MaxBufferSize、MaxArrayLength 的值？默认值非常低，尝试将它们最大化到 2147483647。

还可以尝试在服务上启用跟踪以查看更多错误详细信息。
