将
WCF 服务器和客户端分别部署到不同机器上，可能会触发如下异常。
未处理 System.ServiceModel.Security.SecurityNegotiationException
Message="服务器已拒绝客户端凭据。" Source="mscorlib"
解决方法，就是调整服务器端
Binding 的安全方式，比如设为 "None"。
NetTcpBinding binding = new NetTcpBinding(); binding.Security.Mode
= SecurityMode.None;
ServiceHost host = new ServiceHost(typeof(MyService));
host.AddServiceEndpoint(typeof(IService), binding,
"net.tcp://192.168.10.112:8081");
ServiceMetadataBehavior metadata = new
ServiceMetadataBehavior(); metadata.HttpGetUrl = new
Uri("http://192.168.10.112:8080"); metadata.HttpGetEnabled = true;
host.Description.Behaviors.Add(metadata);
host.Open();
或者在配置文件中设置。
<?xml version="1.0" encoding="utf-8" ?> <configuration>
<system.serviceModel> <bindings>
<netTcpBinding>
<binding
name="NewBinding0">
<security
mode="None" />
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior
name="NewBehavior">
<serviceMetadata
httpGetEnabled="true" httpGetUrl="http://192.168.10.112:8080" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service
behaviorConfiguration="NewBehavior" name="Learn.Library.WCF.MyService">
<endpoint
address="net.tcp://192.168.0.112:8081" binding="netTcpBinding"
bindingConfiguration="NewBinding0"
contract="Learn.Library.WCF.IService">
</endpoint>
</service>
</services>
</system.serviceModel> </configuration>
