实体框架 4 + WCF + Silverlight模型关联问题

发布于 2024-11-09 01:52:29 字数 1354 浏览 0 评论 0原文

我在通过 WCF 服务将实体对象发送到 Silverlight 应用程序时遇到问题。我有一个 Vehicle 类，它工作正常，直到我将多对多关系分配给实体模型中的 Session 类。在服务方面，我成功检索了我的车辆，但是在 Silverlight 应用程序中处理响应时，出现以下错误：

远程服务器返回错误：未找到

我尝试更改延迟加载选项，但它没有改变任何内容......知道吗？

我加入了异常的堆栈跟踪和实体模型的图片

   à System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result)
   à System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result)
   à System.ServiceModel.ClientBase`1.ChannelBase`1.EndInvoke(String methodName, Object[] args, IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.VehiclesManagementServiceClientChannel.EndGetAllVehicles(IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.SFVehicleManagement.VehicleServiceReference.VehiclesManagementService.EndGetAllVehicles(IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.OnEndGetAllVehicles(IAsyncResult result)
   à System.ServiceModel.ClientBase`1.OnAsyncCallCompleted(IAsyncResult result)

我应该添加，我创建了一个全新的项目，只有2个类具有多对多关联和一个非常简单的服务和silverlight应用程序，并得到相同的错误

原文

I have a problem sending my entity objects through a WCF service to a Silverlight application.
I have a Vehicle class and it works fine until I assign a many to many relationship to a Session class in my entity model.
On the service side, I successfully retrieve my vehicles, but when when handling the response in the Silverlight app, I get the following error:

The remote server returned an error: Not Found

I tryed to change the lazy loading options but it didn't change anything...any idea?

EDIT

I join the stacktrace of the exception and a picture of my entity model

   à System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result)
   à System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result)
   à System.ServiceModel.ClientBase`1.ChannelBase`1.EndInvoke(String methodName, Object[] args, IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.VehiclesManagementServiceClientChannel.EndGetAllVehicles(IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.SFVehicleManagement.VehicleServiceReference.VehiclesManagementService.EndGetAllVehicles(IAsyncResult result)
   à SFVehicleManagement.VehicleServiceReference.VehiclesManagementServiceClient.OnEndGetAllVehicles(IAsyncResult result)
   à System.ServiceModel.ClientBase`1.OnAsyncCallCompleted(IAsyncResult result)

Entity model

EDIT2

I should add, I created a brand new project with only 2 classes having a many-to-many association and a very simple service and silverlight app and get the same error
