C# Emailing library

Question

Hey All,

I'm trying to find a c# library to work with my gmail account (any other free email account would work also). I need the library to be able to do the following:

(1) Get ENTIRE emails (sender, subject, text) not just a summary of the text as Atom provides
(2) Get a list of unread emails
(3) Mark emails as read

Alternatively to (2) and (3) if there is some way to provide event driven notifications of a new email that would suffice as well.

I've found libraries that do like 1 or 2, but not all 3 of those.

Any suggestions? Thanks.
