title: Can I edit a Visual Studio 2008 project in 2010 while keeping it a 2008 only project?
body: <p>So on my computer I only have Visual Studio 2010 Express. I need to edit a Visual Studio 2008 project, however it needs to be kept in C# 3.5. </p>
  
  <p>Before I open it in 2010 and accidentally upgrade it, will it be kept in 2008 or C#3.5 format?</p>
  
  <p>I realize I wont be able to use .Net 2010 features, so thats no problem. I just want to make sure if I save my 2008 project using 2010 I will still be able to open it in 2008 and it will work fine.</p>
