.Max() isn't supported, a workaround would be to do an reverse order and take the first.
The URI syntax used by Data Services does not support all functions that are supported by LINQ to Objects or LINQ to SQL. I assume when you are querying this in LINQPad, you are doing a LINQ to SQL query which is why it could work there. However the complexity of your query isn't supported by Data Services which explains your runtime exception in this case.
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.
