title: convert class libraries from asp.net 3.5 to 4
body: <p>I have a Solution that has two class libraries.  I'm trying to convert the whole solution from asp.net 3.5 to 4.</p>
  
  <p>Right now the libraries are in my Visual Studio 2008 projects folder. I've installed VS 2010.  Should I just copy the libraries from the 2008 project folder to my 2010 project folder and open them in VS 2010?  </p>
  
  <p>What is the best practices for this?  The entire solution is in a single folder in my VS 2008 Project folder, and each application and class library is in their own subfolder.</p>
  
  <p>Thank you!</p>
