My developer is trying to convince 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 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!
