Hi... I have to make a 2D game that needs networking (Internet play not for LAN). I chose XNA for the game programming. I was hoping to use "Games for windows Live" service but it's discontinued. I have no prior experience with network game programming. I need some good suggestions on a library that can handle networking. It should be easy to learn because project must be completed by 27th January 2014. Thank you :)

For C#, Lidgren networking library is probably the most mature, stand-alone library.

Thanks. I'll look in to that :)
