You can use Cocos2D-XNA which is a good port of the cocos2d-x project to XNA and C#. You can find the source for Cocos2D-XNA at https://github.com/Cocos2DXNA/cocos2d-xna

Not any I know, but if you know C++ it is easy to learn C#. I found this link; http://i2w.codeplex.com/

I dont know if it is any help at all but still.
