Using C with XNA?

Is it possible to port a game engine like quake 2 to the Xbox through XNA or is there an alternative to XNA for use with C/C++? I have searched the web and was unable to find a concrete answer to this question (but perhaps I wasn't using the correct vocabulary)

XNA is for C#.

I understand that you can use VB.NET in recent versions, but the answer is still no.

Technically yes, but why would you? Oh wait, you already knew that.

I would like to post a link for anyone curious about using C with XNA to a post I made on the App Hub forums (Using plain C with XNA? - App Hub Forums)

I made that post after the one I made on this forum.

EDIT:
And why does it matter why I would want to? Maybe I want to create a game on the quake engine and sell it on Xbox Live, or maybe I would like to learn how to work with managed code. Please don't be so harsh with your criticisms and sarcasm.

You could do it by writing a C++/CLI wrapper but it would be pointless to do so. Performance would be the key issue. As the MSDN thread states and I whole heartedly agree with the tricks used in C cannot be used in C# and vice versa. They are 2 completely different paradigms and 2 completely different mindsets.
