I've been using Visual C# 2008 Express for a good while now, but after comparing it with Visual Studio 2008 Professional, I've decided to 'upgrade' to Visual Studio 2008 Professional, which is easy since I can just grab it for free from DreamSpark (I have a student account there). I cannot upgrade to Visual Studio 2010 Professional as my school hasn't adopted it.
I know that solutions that were developed in Visual C# 2008 Express can be opened and worked on in Visual Studio 2008 Professional, but is it better, or even possible, to convert my solutions so that they show up as Visual Studio 2008 Professional solutions? Or, will they automatically be converted once I start using Professional-only features as I continue to develop my applications?
Hopefully what I'm asking isn't too silly; bear with me, I'm still a VS neophyte :)
