Entity Framework 4 POCO Self Tracking?

No you don't need service but if you don't use the service you should manually say to self tracking entity that it must start tracking changes by calling StartTracking.

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.
