IM chat question

[Tracy Software]

Hi All,

I'm trying to create Instant Messaging software for Windows.
What are the options for the core chat technology?

Is Microsoft Bot Framework a good choice for one-one chat?
Its planed for man-bot so not sure about that...

In addition I don't want to implement it from the ground, WINSOCK etc

I prefer use an already tested platform or library for that
Is DCOM or MSMQ a good choise ?

please advice
