在学习wcf，最近学到wcf事务。自己写了一个示例，就是不会rollback，请大家帮忙看看。
服务器端代码：
namespace Host
{
class Program
{
static void Main(string[] args)
{
ServiceHost host = new ServiceHost(typeof(Calc));

WSHttpBinding wsbinding = new WSHttpBinding();

wsbinding.TransactionFlow = true;
host.AddServiceEndpoint(typeof(ICalc), wsbinding, "http://localhost:8003");

host.Opened += delegate
{
Console.WriteLine("services is open!");
};

host.Open();
Console.ReadKey();
}
}

[ServiceContract]
public interface ICalc
{
[OperationContract]
[TransactionFlow(TransactionFlowOption.Mandatory)]
double Add(double x);
}

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class Calc : ICalc
{
[OperationBehavior(TransactionScopeRequired = true)]
public double Add(double x)
{
Console.WriteLine(Transaction.Current.TransactionInformation.CreationTime);
Console.WriteLine(Transaction.Current.TransactionInformation.LocalIdentifier);
return x + 1;
}
}
}

然后客户端代码：
class Program
{
static void Main(string[] args)
{
WSHttpBinding ws = new WSHttpBinding();
ws.TransactionFlow=true;

ChannelFactory<ICalc> mychannel = new ChannelFactory<ICalc>(ws, "http://localhost:8003");
mychannel.Open();

ICalc myclient = mychannel.CreateChannel();

double x = 3.5;
double y = 0;
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
{
try
{
Console.WriteLine(Transaction.Current.TransactionInformation.CreationTime);
Console.WriteLine(Transaction.Current.TransactionInformation.LocalIdentifier);
y = myclient.Add(x);
throw new Exception("throw new exception");
scope.Complete();
mychannel.Close();
}
catch (Exception ex)
{
Transaction.Current.Rollback();
mychannel.Abort();
Console.WriteLine(ex.Message);
}
}
Console.WriteLine(x);
Console.WriteLine(y);

Console.ReadKey();
}
}

然后每次都是打印
x=3.5
y=4.5

好郁闷啊，我不是有抛出异常了吗？为什么不会Rollback呢。
