  I don't remember that clever words from msdn, but it was like "using of Generic.List or List is recommended, while using of ArrayList should be limited". In my words: I am still replacing all ArrayLists in my [support library](http://quilt.ic.cz/tmp/upl/Soft.htm#support) with generic Lists - just because they don't require CType and such extra code monsters, but also because of that msdn article I read. But - sometimes **just from sentiment **I let there be an arraylist. Probably only place where to use ArrayList very in very legitimate way, is when you need to store list of arrays of different elementtype... then would usage of arraylist helped u later to understand code. But for us, old dogs of ArrayList ;)) this is not possible - we are used to expect anything in arrayList.
