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

I have always disliked the idea because of the expenses. But
he's tryiong none the less. I've been using Movable-type on a variety of websites for about a year and am concerned about switching to
another platform. I have heard very good things about
blogengine.net. Is there a way I can transfer all my wordpress
content into it? Any help would be greatly appreciated!
