In the programs shown on the accompanying slide we have used a binary formatter for serialization of Person and Date object.
Modify the client program to use a so-called Soap formatter in the namespace System.Runtime.Serialization.Formatters.Soap. SOAP is an XML language intended for exchange of XML documents. SOAP is related to the discipline of web services in the area of Internet technology.
After the serialization you should take a look at the file person.dat, which is written and read by the client program.
