WPF, TPL, Producer/Consumer Pattern - Wrong Thread Error?

Ok, actually I just looked at your code again and the problem is simple: You're constructing a new Task instances manually using the constructor overload that takes a state object. There is no constructor overload that takes a TaskScheduler .

You can use Dispatcher to access UI thread like.

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.
