ReadOnlyCollectionBase, Collection, DictionaryBase in VB2005 ?

[Radu]

Hi,

I have VS.NET 2002 and I'm reading about ReadOnlyCollectionBase, Collection,
and DictionaryBase. In the following reference regarding VB2005, I can't
find them:

http://www.dotnet2themax.com/dotnetb...ctions.Generic
http://www.dotnet2themax.com/dotnetb...ns.Specialized

1. Have they been dropped ?

2. Anyway, what could be their use now that (if I understand correctly) VB
supports generics ? I understand that the only purpose of those classes was
to create custom-made, strongly-typed collections, which isn't necessary
anymore with generics, correct ?

Thank you,
Alex

Sorry, I found them, but question 2 still remains:
