title: How can I open a Visual Studio 2008 project in Visual Studio 2010 and leave it in 2008 format?
body: <p>Sometimes I do consultancy work for companies that are still using Visual Studio 2008, but I have 2010 installed.</p>
  
  <p>I assumed (yes, assumption is the mother, father brother and sister of all f-ups!) that I would be able to open 2008 projects in 2010 without having to upgrade them. However, it appears that this is not the case?</p>
  
  <p>Unfortunately, choosing to compile for .NET 3.5 wont solve this problem as the original developers will need to continue to develop the same projects in 2008</p>
