title: Is there a need to convert a Visual Studio Express solution to a Visual Studio Professional solution?
body: <p>I've been using Visual Studio Express for a good while now, but after comparing it with Visual Studio Professional, I've decided to 'upgrade' to Visual Studio Professional, which is easy since I can just grab it for free from <a href="http://www.dreamspark.com" rel="nofollow noreferrer">DreamSpark</a> (I have a student account there).</p>
  
  <p>I know that solutions that were developed in VS Express can be opened and worked on in VS Professional, but is it better, or even possible, to convert my solutions so that they show up as VS Professional solutions? Or, will they automatically be converted once I start using Professional-only features as I continue to develop my applications?</p>
