SYMPTOMS
When you try to serialize a custom data type in an application that is built on the Microsoft .NET Framework 2.0, you receive an exception error message that resembles the following:
Unable to generate a temporary class (result=1).
error CS0200: Property or indexer 'XmlSerializationIssueKB928365.SampleData.Name ListSpecified' cannot be assigned to -- it is read only
Error Stack:

This problem occurs after you install the MS07-040 update.
CAUSE
This issue occurs because the *Specified property is set to read-only when the custom type defines the *Specified property for a serialized property.
Note The *Specified property is a feature in the XmlSerializer class that controls how a property is generated in XML.
