title: Make a backward compatible project in Visual studio 2017?
body: <p>At school we are using Visual Studio 2015 but at home I have Visual studio 2017. When I start project at home there is a lot of error happening when I get back to school. </p>
  
  <p>Our homeworks are made so they can both be made in the two versions. So is there any way I could se a parameter so my projects made with 2017 version of visual could be fully compatible with the 2015 version?</p>
  
  <p>Thanks in advance.</p>
