Lately I have been playing around with serializing and deserializing of objects, and I stumbled upon a very weird behavior. I was trying to serialize a certain object that was implementing the INotifyPropertyChanged Interface. I marked the object as [Serializable] and used the following method to serialize it:

   1: public void SerializeNow()

   2: {

   3:    Stream s = File.Create("Data.dat");

   4:    BinaryFormatter b = new BinaryFormatter();

   5:    b.Serialize(s, data);

   6:    s.Close();

   7: }

Serialization is the process of saving an object onto a storage medium (such as a file, or a memory buffer) or transmiting it across a network connection link in binary form.
The .NET Framework provides an easy-to-use serialization mechanism by using the [Serializable] attribute. If so why do we need the ISerializable interface? Lets compare to see [...]
