• .NET Development Serialization framework improvements in .Net 2.0? (MulticastDelegate)

  I have re-implemented an IFormatter for the project NGrid . The code can be seen on this page . I have found such tasks very tedious with the current design of the serialization framework in .Net 1.1. Here below, the list of the hard points. IMessage serialization (and the derived classes) is pure hell. As the consequence even the BinaryFormatter fails when it tries to serialize an IMessage containing itself an other IMessage.
