    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 nervous
    about switching to another platform. I have heard very good things about blogengine.net.
    Is there a way I can import all my wordpress content into it?
    Any kind of help would be greatly appreciated!
