WCF分布式开发常见错误(14):无效的操作异常,At least one operation on the ...

WCF事务编程过程中，会出现这个操作无效异常。信息如下：
At least one operation on the 'WCFServiceTransaction1' contract is configured with the TransactionFlowAttribute attribute set to Mandatory but the channel's binding 'NetTcpBinding' is not configured with a TransactionFlowBindingElement. The TransactionFlowAttribute attribute set to Mandatory cannot be used without a TransactionFlowBindingElement.
异常界面如图：



[align=left]我是在调试客户端事务模式的时候出现的错误，服务契约和服务类的代码如下：[/align]

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Runtime.Serialization;
using System.Transactions;
using System.Diagnostics;
//ServiceContract 属性以及 Indigo 使用的所有其他属性均在 System.ServiceModel 命名空间中定义，
//因此本例开头使用 using 语句来引用该命名空间。

namespace WCFService
{
//1.服务契约
[ServiceContract(Namespace = "http://www.cnblogs.com/frank_xl/")]
public interface IWCFServiceTransaction1
{
//操作契约
[OperationContract]
//强制事务流，使用客户端事务
//[TransactionFlow(TransactionFlowAttribute
[TransactionFlow(TransactionFlowOption.Mandatory)]
bool AddNewData(string name);

}
//2.服务类，实现契约
//事务有10分钟的超时限制
//[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
[ServiceBehavior(IncludeExceptionDetailInFaults = true, TransactionTimeout = "00:30:00")]
public class WCFServiceTransaction1 : IWCFServiceTransaction1
{
//实现接口定义的方法
//需要事务环境，启动事务
[OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
public bool AddNewData(string name)
{
Transaction transaction = Transaction.Current;
Debug.Assert(System.Transactions.Transaction.Current.TransactionInformation.DistributedIdentifier!=Guid.Empty);
Console.WriteLine("Create a new Transaction at {0}", System.Transactions.Transaction.Current.TransactionInformation.CreationTime);
Console.WriteLine("WCFService 1 Transaction Status is {0}", System.Transactions.Transaction.Current.TransactionInformation.Status);
Console.WriteLine("WCFService 1 Transaction LocalIdentifier is {0}", System.Transactions.Transaction.Current.TransactionInformation.LocalIdentifier);
Console.WriteLine("WCFService 1 Transaction DistributedIdentifier is {0}", System.Transactions.Transaction.Current.TransactionInformation.DistributedIdentifier);

//using (System.Transactions.TransactionScope ts = new System.Transactions.TransactionScope())
//{
try
{
using (userTableAdapter adapter = new userTableAdapter())
{
if (1 == adapter.CreateUser(name))
{
Console.WriteLine("Calling WCF Transaction sucessfullyname length is:{0}", name.Length);
}
else
{
Console.WriteLine("Calling WCF Transaction unsucessfullyname length is:{0}", name.Length);
//return false;
}
}
}
catch (Exception e)
{
Console.WriteLine("Calling WCF Transaction error:{0}", e.Message);
throw e;
//return false;
}

//ts.Complete();
return true;

}
}
}
[align=left]我查阅到的资料：
1.http://social.msdn.microsoft.com/Forums/en-US/windowstransactionsprogramming/thread/d3020922-92b3-4dc5-ab22-b8fe34cbf40e；这个是属性没定义在操作契约上。
2.http://blogs.msdn.com/thelever/archive/2007/03/29/configuration-of-transactions-of-use-in-wcf.aspx；这个建议更换[TransactionFlow(TransactionFlowOption.Allowed)].
可以解决问题。但是我不能这样。
我这里是为了测试客户端事务模式写的代码。
所以大家都什么好的解决办法~谢谢[/align]
[align=left]3.已经找到解决办法：[/align]
[align=left]使用配置文件方式：[/align]
[align=left]添加一个绑定协议节点，。也可以使用编程方式。这里给出代码：[/align]

<bindings>
<netTcpBinding >
<binding name="netTcpBindingTcp" transactionFlow="true" transactionProtocol="WSAtomicTransactionOctober2004" >

<!--<reliableSession enabled="true" ordered="true"/>
<security mode="None"></security>-->
</binding>
</netTcpBinding>
</bindings>
[align=left]然后在服务终结点里使用这个配置：[/align]

<endpoint
address="net.tcp://localhost:9002/WCFServiceTransaction2"
bindingConfiguration="netTcpBindingTcp"
binding="netTcpBinding"
contract="WCFService.IWCFServiceTransaction2">
</endpoint>
