My programmer is trying to convince me to move to .net from PHP.

I have always disliked the idea because of the costs.
But he's tryiong none the less. I've been using
WordPress on several websites for about a year
and am anxious about switching to another platform. I have heard very good things about blogengine.net.
Is there a way I can import all my wordpress content into it?

Any help would be greatly appreciated!
