My coder 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 numerous websites for about a year and am worried
about switching to another platform. I have heard excellent things about blogengine.net.
Is there a way I can import all my wordpress posts into it?

Any kind of help would be greatly appreciated!
