My developer is trying to persuade 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 
number of websites for about a year and am anxious about switching to another 
platform. I have heard great things about blogengine.net. Is there a way I can import all my wordpress posts into it?
Any kind of help would be really appreciated!
