WebClient does not implement the iDisposable interface so there is nothing special that needs to be done to allow for proper garbage collection. When the CLR detects that there are no current references to the object, it will be scheduled for garbage collection. Of course you don't know just when that will occur so the memory may or may not (most likely not) be freed up immediately.
I see 2 problems. First of all, webclient isnt disposed in all possible situations, secondly a reference to WebClient will be maintained since you never unsubscribe the event.
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.
