My coder 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 several websites for about a year and
am anxious about switching to another platform.
I have heard fantastic things about blogengine.net.
Is there a way I can transfer all my wordpress posts into it?

Any help would be really appreciated!
