We have the following classes and WCF service (using protobuf-net for serialization):
[DataContract]
[KnownType(typeof(NamedViewModel))]
public class NamedViewModel<TKey> : IViewModel
{
[DataMember]
public virtual TKey Id { get; set; }
[DataMember]
public virtual string Name { get; set; }
}
[DataContract]
[KnownType(typeof(ScheduleTemplateViewModel))]
public class NamedViewModel : NamedViewModel<int>
{
}
[DataContract]
public class ScheduleTemplateViewModel : NamedViewModel
{
[DataMember]
public string Comment { get; set; }
}
[DataContract]
public class Container
{
[DataMember]
public IEnumerable<ScheduleTemplateViewModel> Templates { get; set; }
}
[ServiceContract]
public interface IService
{
[OperationContract]
Container Get();
}
public class Service : IService
{
public IEnumerable<Container> Get()
{
return new Container { Templates = Enumerable.Range(1, 10)
.Select(i => CreateTemplate()).ToArray() };
}
private void ScheduleTemplateViewModel CreateTemplate()
{
var instance = WindsorContainer.Resolve<ScheduleTemplateViewModel>();
// populate instance
return instance;
}
}
We have two problems:
We get an exception during serialization that the Castle DynamicProxy type for ScheduleTemplateViewModel is unexpected. We noticed that there is custom code in protobuf-net to handle NHibernate and EntityFramework proxies...but not Castle DynamicProxies. We worked around this by adding an additional case statement in the protobuf-net source code to check for Castle's IProxyTargetAccessor type...but it would be nice if there were a way of handling this without modifying the protobuf-net source code...
Members on ScheduleTemplateViewModel (namely Comment) are serialized correctly...but base class Members are not. We already have the InferTagFromNameDefault set to true on RuntimeTypeModel.Default.
