Why can I serialize .NET Framework classes like exceptions and fonts?
The XmlSerializer is primarily designed with two goals in mind: XML data binding to XSD compliant data structures and operation without any special code access privileges. These two goals work against the XmlSerializer as a general-purpose object persistence solution for some kinds of objects. General purpose serialization may require accessing private fields, by-passing the framework’s standard object construction process, and so on, which in turn requires special privileges. The SoapFormatter from the System.Runtime.Serialization.Formatters.Soap namespace provides an alternative that is not subject to these restrictions, but requires full trust to operate. It also produces an XML format, a generation of which is customizable using the attributes in the System.Runtime.Remoting.Metadata namespace. The BinaryFormatter from the System.Runtime.Serialization.Formatters.Binary namespace can also be used as a mechanism to provide simple object persistence and transport for situations where X
