Description

Is essentially a modified version of Type.IsSubClassOf that supports checking whether a class derives from a generic base-class without specifying the type parameters. For instance, it supports typeof(List<>) to see if a class derives from the List<T> class. The actual code was borrowed from http://stackoverflow.com/questions/457676/c-reflection-check-if-a-class-is-derived-from-a-generic-class.
