title: Opening a Visual Studios 2015 project with 2013
body: <p>I was using the trial of Visual Studios 2015 to develop a C# app. Now my trial has expired. I would like to continue developing the app in my licensed version of Visual Studios 2013. However, I can't seem to open the <code>.sln</code>. The file opens, but it say "Incompatible". Aside from copy pasting all of the code and re-configuring everything, is there another way I can open it?</p>
