1.Prefer the binary formatter.
2.Mark serialization event-handling methods as private.
3.Use the generic IGenericFormatter interface.
4.Always mark non-sealed classes as serializable.
5.When implementing IDeserializationCallback on a non-sealed class, make sure to do so in a way that allows subclasses to call the base class implementation of OnDeserialization( ).
6.Always mark unserializable member variables as non-serializable.
7.Always mark delegates on a serialized class as non-serializable fields:
[Serializable]
public class MyClass
{
[field:NonSerialized]
public event EventHandler MyEvent;
}
