My developer 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 WordPress on 
a variety of websites for about a year and 
am concerned about switching to another platform. I have heard great things about blogengine.net.
Is there a way I can transfer all my wordpress content into it?

Any kind of help would be greatly appreciated!
