客户端的事务

我有一个大问题使用或理解使用wsdualhttpbinding WCF事务。

我有这样的东西:

IService:

[ServiceContract]
public interface IService
{
  //...
  [OperationContract]
  [ApplyDataContractResolver]
  [TransactionFlow(TransactionFlowOption.Mandatory)] 
  bool SaveDevice(Device device);
  //...
}

Service.svc.cs:

[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
  public class Service : IService
  {
   [OperationBehavior(TransactionScopeRequired = true)]
   public bool SaveDevice(Device device)
   {
            bool temp = false;
            Transaction transaction = Transaction.Current;
            using (EntityConn context = new EntityConn())
            {
                try
                {
                  //....
                }
             }
    }
   }

Model.cs 所以这里我在我的客户端，并尝试执行一个操作与事务需求:

if (Transaction.Current.TransactionInformation.DistributedIdentifier == Guid.Empty)
        {
            using (var scope = new TransactionScope(TransactionScopeOption.Suppress))
            {
                try
                {
                   //do some stuff
                }
            }
          }

我得到一个错误:事务。电流为空

1. 这条路对吗?
2. 如果不是，我该如何解决?

谢谢你的帮助

EDIT:我只需要把if放在using

之后

    using (var scope = new TransactionScope(TransactionScopeOption.Suppress))
    {
     if (Transaction.Current.TransactionInformation.DistributedIdentifier == Guid.Empty)
     {
            try
            {
               //do some stuff
            }
     }
    }

using (TransactionScope tran = new TransactionScope())
{
    if (Transaction.Current.TransactionInformation.DistributedIdentifier == Guid.Empty)
    {
        // ambient transaction is not escalated; exclude this operation from the ambient transaction
        using (TransactionScope tran2 = new TransactionScope(TransactionScopeOption.Suppress))
        {
            // do some stuff
        }
    }
    else
    {
        // ambient transaction is escalated
        // do some other stuff
    }
}
