Last time I looked at XNA it was at version 4 and you could use it to develop C# games that ran on Windows, or Windows Phone, or Xbox 360.
Just been poking around again and I can't get any sense out of what the current state of play is.
The emphasis is very very much on Windows phone 7.5, then to a lesser extent 360, and for Windows you just get pointed at the DirectX SDK.
Has it been re-envisioned again? At some point I remember the C# version disappeared and you only had the C++ version, I sort of lost interest then.
Thanks
