My developer is trying to convince 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 a variety of websites for about a year and am worried about switching to another platform. I have heard very good things about blogengine.net. Is there a way I can transfer all my wordpress content into it? Any help would be really appreciated!
