Your best bet, outside of database solutions, is to join using LINQ (to objects) after execution.
You could try using a GetTable command. I think this loads all of contextB. TableB's data first, not 100% sure on that though.
I don't have an environment set up to play around in or test this out so let me know if it works =).
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.
