Question

I’m using a WCF service with an code, which was generated from a mex endpoint.

I would like to be able serialize the classes, which were automatically generated.

My problem is, that those auto-generated classes implement System.ComponentModel.INotifyPropertyChanged interface, and occasionally when serializing them, I’m getting following exception:

Type 'System.ComponentModel.PropertyChangedEventManager' in 
Assembly 'WindowsBase, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35' is not marked as serializable.

Normally I would deal with this exception by adding [NonSerializable] to the PropertyChanged event, but here the code is auto-generated, and I don’t want to change it.

What is the best way to deal with this problem?

It sounds like you are using BinaryFormatter – however, WCF types are intended for serialization with DataContractSerializer, or related serializers (NetDataContractSerializer, protobuf-net, etc). Try using DataContractSerializer instead – your problem should evaporate.
