Use the . Include method to load the related entities. For example: from photo in entitiesContext.

Photo . Include("UserReference") . Include("PhotoComments") etc.

When creating your ObjectQuery, call the Include method, passing in the name of the subentity that you want to load automatically. You can chain calls to Include if you have multiple subentities that you want to load. See this article for more information.

Maybe change the select to something like: select new {photo, photo. UserReference, photo. PhotoComments}.

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.
