title: What cultures are supported by the CultureInfo class in .NET 3.5?
body: <p>I need a list of cultures that are supported by .NET 3.5, regardless of the OS used. 
  This seems to be quite a struggle to obtain, though I am not sure why!</p>
  
  <p><strong>Edit:</strong> Arghh, I was not aware that it is dependent on the OS, that would explain the lack of documentation. Any ideas on what is supported by Mac/Linux OS as well?</p>
  
  <p>Thanks :)</p>
