My programmer is trying to persuade 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 
worried about switching to another platform. I have heard good things about 
blogengine.net. Is there a way I can import all 
my wordpress content into it? Any kind of help would be really appreciated!
