后銳方法邊界方面不適用於WCF服務類

Question

我有一個自定義方面，我試圖添加到服務中以自動記錄所有錯誤並發送適當的錯誤消息，但是當我嘗試將其應用於類並將Attributetargetelements設置為Multicast.method或將其應用於單個方法時，我的服務返回500錯誤並顯示錯誤消息

有辦法解決這個問題嗎？

我的代碼如下

服務方面

[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);
        }
    }
}

並將其應用於課堂

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

一旦從代碼中刪除了服務方面，它就會按預期工作。

編輯

設置[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]來替換[Serializable屬性

我已經考慮過了，但是問題是由於ServiceAspect的[Serializable]屬性，服務無法啟動。 將可序列化的屬性更改為[OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))]返回Method not found: 'Void API.Model.Infrastructure.Aspect.ServiceAspect.OnException(PostSharp.Aspects.MethodExecutionArgs

請看一下這個討論 。 看來您的項目中可能有兩個不同版本的PostSharp.dll。
