Postsharp Methodbounddry方面无法与WCF服务类一起使用

Question

我有一个自定义方面，我正试图添加到我的服务中，以自动记录所有错误并发送适当的错误消息，但当我尝试将其应用于类并将Attributetargetelements设置为Multicast.method或应用于单个方法时，我的服务返回一个500错误，错误消息为

有办法绕过这一点吗

我的代码如下

服务方面

[Serializable]
public class ServiceAspect : OnMethodBoundaryAspect
{
//create logger
private static readonly log4net.ILog log = LogManager.GetLogger(typeof(BrokerServiceAspect).Name);//
public override void OnException(MethodExecutionArgs args)
{
log.Error(args.Exception.Message, args.Exception);//log specific type of error
args.FlowBehavior = FlowBehavior.Return;//return excution
if (args.Exception is NullReferenceException)
{
args.ReturnValue = new FaultException(BrokerFaultCodes.NullExceptionCode);
}
else if (args.Exception is Exception)
{
args.ReturnValue = new FaultException(BrokerFaultCodes.GenericException);
}
}
}

并将其应用于类

[ServiceAspect(AttributeTargetElements = MulticastTargets.Method)]
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, InstanceContextMode = InstanceContextMode.PerCall,IncludeExceptionDetailInFaults = true)]
public class APIService : ServiceBase,IAPIService
{

一旦我从代码中删除了服务方面，它就会按预期工作。

编辑

设置[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]以替换[Serializable属性现在返回

我已经考虑过了，但问题是由于ServiceAspect上的[Serializable]属性，服务没有启动。将可序列化属性更改为[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]返回Method not found: 'Void API.Model.Infrastructure.Aspect.ServiceAspect.OnException(PostSharp.Aspects.MethodExecutionArgs

请看一下这次讨论。您的项目中可能有两个不同版本的PostSharp.dll。
