  1. My programmer 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 a number of websites for about a year and am anxious about switching to another platform. I have heard good things about blogengine.net. Is there a way I can import all my wordpress content into it? Any help would be greatly appreciated!
