azure-service-fabric - 使用 Service Fabric 远程处理捕获自定义异常

Question

以下文档详细介绍了 Service Fabric 远程处理中的异常处理(我使用 V2):

https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-communication-remoting#remoting-exception-handling

它有以下段落:

All remote exceptions thrown by the service API are sent back to the client as AggregateException. RemoteExceptions should be DataContract serializable; if they are not, the proxy API throws ServiceException with the serialization error in it.

我在服务之间共享的 .NET Core 类库中创建了以下异常:

[DataContract]
public class DuplicateEntityException : Exception
{
    public DuplicateEntityException(string message = "Duplicate entity.") : base(message) { }
}

在调用的服务中抛出异常后，我收到以下消息:

System.AggregateException: One or more errors occurred. (The exception DuplicateEntityException was unhandled on the service and could not be serialized for transferring to the client.

如果我只是抛出 Exception 它会正确序列化。

如果能帮助我的异常类 DataContract 可序列化，我们将不胜感激。

我所要做的就是:

[Serializable()]
public class DuplicateEntityException : Exception, ISerializable
{
    public DuplicateEntityException(string message = "Duplicate entity.") : base(message) { }

    public DuplicateEntityException(SerializationInfo info, StreamingContext context) : base(info, context) { }
}
