This assembly contains the DLR. If you need to use dynamic dispatching in your application it must be referenced. It is added as reference by default when you start a new application in VS 2010 (Console, WinForms, ASP.NET, Class library).
This error always happens when you use some feature about dynamic object. Complier will throw error about missing Microsoft.CSharp. Dll and System.Core.dll.
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.
