Does LINQ to SQL support POCO?

Question

If I want to work with an object and use LINQ to SQL, what (if anything) do I need to add to my object classes so that my application can talk to the data store? (don't discuss repository templates here, as I'm just looking for what is required inside my business objects)

Answer 1

Besides using the LINQ-to-SQL constructor and creating “almost POCO” classes (decorated with a bunch of attributes for matching), you can also use an external XML mapping file (like NHibernate) to achieve the same thing that allows you to maintain the true POCO classes "without any additional attributes or anything else.

See here for more information:

• Linq to SQL - mapping tables to objects
• Using an External Mapping File with Linq To SQL DataContext
