If this question/observation goes outside the scope of the book, just ignore it, but I find this interesting. I am trying to use the techniques demonstrated in the book to my own project.

I defined a class that mirrored the structure of a table, with some constructors and get/sets - nothing more. The class file existed in the project but not otherwise in use.

Later, I created a linq to Sql class and on the table and brought up the Object Relational Designer when a whole pile of runtime errors occurred referencing my class file - all about duplicate constructors and name clashes.

I am assuming that the linq to sql class setup created some source code very similar to my own? Does that mean having my hand coded class and a linq to sql class are mutually exclusive?

Got it now.

Hi there,

Sorry for my late reply. Bit busy....

Anyway, glad you figured it out. What did you do? Put your class in a separate namespace so the two don't clash anymore?

If you want to extend the class that is defined by L2S, you can also create a partial class with the same name and namespace as the L2S class. E.g.:

public partical class Picture {}

Cheers,

Imar
