DataContractSerializer doesn't call my constructor?

Question

I just realized something crazy, which I assumed to be completely impossible : when deserializing an object, the DataContractSerializer doesn\'t call the constructor

Answer 1

DataContractSerializer (like BinaryFormatter) doesn't use any constructor. It creates the object as empty memory.

For example:

    Type type = typeof(Customer);
    object obj = System.Runtime.Serialization.
        FormatterServices.GetUninitializedObject(type);

The assumption is that the deserialization process (or callbacks if necessary) will fully initialize it.
