My developer 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 numerous 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 posts into it? Any help would be really appreciated!
