Basically, it has support for allowing runtime resolution of types if they are declared as having the "dynamic" type. But it's even better, the specification for how that resolution happens is defined in a library. This way you can work directly with dynamic values without having to cast them first (e.g. imagine just "dotting your way" through a JSON document and parse it on-demand). See For how it's used: http://msdn.microsoft.com/en-us/library/vstudio/dd264736.aspx For how to implement dynamic libraries (e.g. decide what happens when a field is accessed, or a method is called, on your dynamic objects): http://msdn.microsoft.com/en-us/library/vstudio/system.dynamic.dynamicobject.aspx -- Sebastian Sylvan
