Assembly: mscorlib (in mscorlib.dll)
This attribute allows you to specify that new fields in a serializable type (a type to which the SerializableAttribute is applied to) are ignored by the BinaryFormatter or the SoapFormatter. This enables version-tolerant serialization of types created for older versions of an application that serializes data. For example, when the formatters encounter a stream produced by a version that does not include the new fields, no exception is thrown, and the existing data on the older type is processed as normal.
