My coder 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 a variety of 
websites for about a year and am nervous about switching to another platform.
I have heard excellent things about blogengine.net. Is there a way 
I can import all my wordpress content into it? Any help would 
be greatly appreciated!
