[Mono-list] how to use System.Collections.Generic

[Ryan Heaton]

Hi all.  Sorry for the newbie question, but I can't seem to use the
System.Collections.Generic.List class.  What assembly reference do I
need?  I'm on Ubuntu Intrepid, using "gmcs". Here's my error:

error CS0234: The type or namespace name `List' does not exist in the
namespace `System.Collections.Generic'. Are you missing an assembly
reference?

Thanks!
