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 WordPress on various 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 import all my wordpress content into it?
Any help would be really appreciated!
