LINQ to SQL Serialization

Problem:

• LINQ to SQL classes do not support binary serialization. Although I can manually modify them to meet my needs, it is a very time-consuming job, and difficult to maintain if the table is changed in the future.
• LINQ to SQL classes cannot be serialized by XML serializer if there is a relationship between tables.
