Deserialization backwards compatibility

Question

I am trying to deserialize \"SomeClass\" with an older version of an application. I get this below exception

System.Runtime.Serialization.Serializatio

Answer 1

As an advisory to people investigating this issue "before it is too late"... I strongly advise against persisting via BinaryFormatter. It is OK for transient transfer between 2 app-domains that are in sync, but that is about it IMO. Other serialization tools exist that don't have these issues. In terms of binary, protobuf-net is a pretty reasonable option - allowing add/remove/rename etc without pain.
