C# 无法连接到远程WCF服务-SecurityNegotiationException

我从一开始，我跟着。我设法在一台机器上运行Getting Started示例，并在不同的机器上部署客户机和服务并远程访问该服务

我的目标是实施该计划。我设法在一台机器上运行它，没有任何大问题。但是，当我在不同的计算机上部署客户机和服务时，我的客户机无法连接到该服务。我得到以下例外情况：

System.ServiceModel.Security.SecurityNegotiationException was unhandled
  Message=The caller was not authenticated by the service.
  Source=mscorlib

（如有必要，我可以共享堆栈跟踪。）

以下是我的配置：

我一直在寻找解决办法，但什么都不管用。我试图找到一种在服务端禁用安全性/身份验证的方法（只是为了让它工作），但在这方面也没有成功

如何解决此问题？

默认情况下使用Windows身份验证。如果您现在不需要此身份验证，可以更改配置以将其关闭：

<configuration>
  <system.serviceModel>
<bindings>
  <wsDualHttpBinding>
    <binding name="wsHttpDual">
      <security mode="None">
        <transport clientCredentialType="None" protectionLevel="EncryptAndSign" />
        <message clientCredentialType="None" algorithmSuite="Default" />
      </security>
    </binding>
  </wsDualHttpBinding>
</bindings>
    <protocolMapping>
      <add scheme="http" binding="wsDualHttpBinding" bindingConfiguration="wsHttpDual"/>
    </protocolMapping>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

更改客户端配置中的安全部分的方法相同：

      <security mode="None">
        <transport clientCredentialType="None" protectionLevel="EncryptAndSign" />
        <message clientCredentialType="None" algorithmSuite="Default" />
      </security>

您的配置中实际设置了吗？@ValtasarIII是，先生。：）只是上面代码中的一个小问题。wsDualHttpBinding不支持传输安全性。因此，如果我们在没有传输安全性的情况下使用这些配置，则上述配置是正确的。Rest很好，似乎正在为我工作。我已经尝试过了，但现在我收到了以下错误：“打开操作未在分配的超时00:00:59.7710000内完成。分配给此操作的时间可能是更长超时的一部分。”。请提出一些建议。
