Single vs. multiple Linq2sql repositories?

Linq2Sql uses lazy loading to get additional information. I believe it can be configured to fetch all at once, but that is not the default behavior. If you ask for a user, you will not get events unless you specifically ask for them.

I have a project with 100+ tables in the dbml, as far as I can tell this does not effect the the time to instanciate the datacontext class.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
