WCF FaultContract 导致更新服务引用失败 [英] WCF FaultContract causes Update Service Reference to fail

问题描述

我有一个用 [ServiceContract] 和 [OperationContract] 属性修饰的 IServiceFacade 接口.当我从解决方案资源管理器通过 VS2005 执行更新服务参考时，它工作正常.现在我想将 [FaultContract] 属性添加到 IServiceFacade 接口中的所有方法.当我将属性添加到几个方法时，更新服务引用仍然有效.然而，如果装饰方法的数量达到一定数量，则服务引用的更新失败.好像和用错误契约修饰的方法没有任何关系.

I have an IServiceFacade interface decorated with a [ServiceContract] and [OperationContract] attributes. When I perform Update Service Reference via VS2005 from the solution explorer, it works fine. Now I want to add [FaultContract] attributes to all of the methods in the IServiceFacade interface. When I add the attributes to a couple of methods, Update Service Reference still works. If however the number of decorated methods reach a certain number, the update of the service reference fails. It doesn't seem to have anything to do with the methods that are decorated with fault contracts.

这是服务合同:

[ServiceContract]
public interface IServicesFacade
{

    [OperationContract]
    [FaultContract(typeof(SecurityFault))]
    bool UserHasWriteRights();
    ...
}

这是错误的实现:

[DataContract]
public class SecurityFault
{
    private string _message;

    public SecurityFault (string message)
    {
        _message = message;    
    }

    [DataMember]
    public string Message
    {
        get { return _message; }
        private set { _message = value;}
    }
}

推荐答案

好的，我找到原因和解决方案了.基本上我的合同规模太大了.解决此问题的一种方法是将 svcutil.exe.config 文件添加到 svcutil 所在的目录¹.配置应如下所示:

Ok, I found the reason and solution. Basically my contract size got too large. A way to fix this is to add a svcutil.exe.config file to the directory where the svcutil is located¹. The config should look something like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>

    <client>
        <endpoint name="net.tcp" binding="netTcpBinding" bindingConfiguration="GenericBinding"
        contract="IMetadataExchange" />
        <endpoint name="http" binding="wsHttpBinding" bindingConfiguration="SecureBinding" contract="IMetadataExchange" />
    </client>

    <bindings>

        <netTcpBinding>
            <binding name="GenericBinding" maxBufferPoolSize="2147483647"
            maxReceivedMessageSize="2147483647" >
                <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                maxNameTableCharCount="2147483647" />
                <security mode="None"/>
            </binding>
        </netTcpBinding>

        <wsHttpBinding>
            <binding name="SecureBinding" maxBufferPoolSize="2147483647"
            maxReceivedMessageSize="2147483647" >
                <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                maxNameTableCharCount="2147483647" />
                <security mode="Message">
                    <transport clientCredentialType="Windows" />
                </security>
            </binding>
        </wsHttpBinding>
    </bindings>
</system.serviceModel>
</configuration>
