Question

我有一个大型类，其中有许多函数作为WCF服务公开，它也有一个mex endpiont。现在，当我尝试在Visual Studio 2010中添加对该服务的引用时，我收到以下错误：

mex error

除了减少方法计数之外，我还能做些什么来使这个错误消失吗？

这是我用于mex端点的代码：

        // Check to see if the service host already has a ServiceMetadataBehavior
        ServiceMetadataBehavior smb = svh.Description.Behaviors.Find<ServiceMetadataBehavior>();
        // If not, add one
        if (smb == null)
            smb = new ServiceMetadataBehavior();
        //smb.HttpGetEnabled = true;
        smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
        svh.Description.Behaviors.Add(smb);

        // Add MEX endpoint
        svh.AddServiceEndpoint(
          ServiceMetadataBehavior.MexContractName,
          MetadataExchangeBindings.CreateMexTcpBinding(),
          location+"/mex"
        );

您可以使用配置文件中readerQuota节点上的maxNameTableCharCount属性覆盖它。

这是＆lt; readerQuote＆gt;文件：http://msdn.microsoft.com/en-us/library/ms731325.aspx

这是自动生成的客户端配置的示例。默认值为16384。

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="YOUR_NAME" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="268438456" maxBufferPoolSize="524288" maxReceivedMessageSize="268438456"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
          useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
            maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="Transport">
            <transport clientCredentialType="Basic" proxyCredentialType="None"
              realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="YOUR_ADDRESS" binding="basicHttpBinding"
        bindingConfiguration="YOUR_ENDPOINT" contract="YOUR_CONTRACT"
        name="YOUR_NAME" />
    </client>
  </system.serviceModel>

如何使用可导入VS 2010的许多功能来制作大型WCF服务？
