title: Are there reasons to use Visual Studio 2005 when 2008 is available?
body: <p>What reasons are there for continuing to run Visual Studio 2005 when 2008 is available?  </p>
  
  <p>I work on a project where the environment is dictated to be Visual Studio 2005.  Are there good technical reasons for this?  Can I use Visual Studio 2008 and build an app that is 100% indistinguishable from the same app build with Visual Studio 2005?</p>
