XNA Poker Game

What I need is a simple XNA Poker Game framework done. There is no need to include fancy graphics (I can do that myself). Usage of placeholders is just fine. This game is not mean to be played Online but offline instead...so an AI Opponent framework is a plus (doesn't need to be an extremely complicated opponet but something basic where I can build from later). Ideally, the opponents should come as separate object, like a plugin or something. The purpose is to be able to build opponents easily.
