As I understand it, support for LINQ to SQL isn't going anywhere, but most of the resources for ongoing development will be devoted to LINQ to Entities. I think you're safe going whichever direction looks like the better choice. If it's LINQ to SQL, go for it as long as it has everything you need- don't count on new features.
If you are deciding between those 2, and can use VS2010, definitely go with Entity Framework 4 now that is properly supports lazy loading, POCO objects, and code only models.
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.
