Is there a quick way to remove using statements in C#?

Question

Is there a quick way to determine whether you are using certain namespaces in your application. I want to remove all the unneccessary using statements like using System.Reflection and so on, but I need a way to determine if I am using those libraries or not. I know that the tool Resharper does this for you, but is there a quick and dirty and Free way to do this?

Answer 1

Visual Studio 2008 will also do this for you, right click in your class file and select "Organize Usings" -> "Remove and Sort".
