更改 TransactedReceiveScope 活动中的事务隔离级别

Question

由于数据库中存在锁定问题，我们希望更改 TransactedReceiveScope 隔离级别从 Serialized 到 ReadCommissed。我们使用 ServiceBehavior< 来完成此操作/a> 扩展：

 public class ReadCommittedServiceBehaviour : BehaviorExtensionElement ,IServiceBehavior
{

        public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters) { }
        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
        {
            serviceDescription.Behaviors.Add(new ServiceBehaviorAttribute() { TransactionIsolationLevel = IsolationLevel.ReadCommitted });
        }
        public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) {}
        public override Type BehaviorType
        {
            get { return typeof(ReadCommittedServiceBehaviour); }
        }

        protected override object CreateBehavior()
        {
            return new ReadCommittedServiceBehaviour();
        }
}

我想知道的是...这在 AppFabric 级别是一个好主意吗？我担心持久性数据库中的实例创建。

谢谢
