Question

我第一次使用WCF设施主持一对夫妇服务器，在控制台应用程序（便于调试）和IIS（用于）生产）。这些服务使用 net.msmq 端点。

这就是我在控制台应用程序（简化）中托管服务的方式：

using (var host = new DefaultServiceHostFactory() 
                    .CreateServiceHost(typeof(MyService).AssemblyQualifiedName, 
                                       new Uri[0])) 
    host.Open();

以下是它的注册方式：

container.Register(Component.For<UserRequestService>()
                            .LifestylePerWcfOperation())

我想做的是为所有操作添加以下行为：

[OperationBehavior(TransactionScopeRequired = true,
                   TransactionAutoComplete = true)]

这是我试过的：

container.Register(Component.For<IOperationBehavior>() 
                            .UsingFactoryMethod(
                                x => new OperationBehaviorAttribute 
                                { 
                                    TransactionScopeRequired = true, 
                                    TransactionAutoComplete = true 
                                }));

但这会导致异常：

System.ArgumentException: The value could not be added to the collection, as the collection already contains an item of the same type: 'System.ServiceModel.OperationBehaviorAttribute'. This collection only supports one instance of each type.
Parameter name: item

   at Castle.Facilities.WcfIntegration.WindsorServiceHostFactory`1.CreateServiceHost(String constructorString, Uri[] baseAddresses)
   at Program.Main()

有什么想法吗？

使用WCF工具添加操作行为
