title: C# 7.0 'out variables' in Visual Studio 2015
body: <p>I would like to compile C# 7.0 solution in Visual Studio 2015, but I have syntax error:</p>
  
  <p><a href="https://i.stack.imgur.com/fNhuL.png" rel="nofollow noreferrer">Error</a></p>
  
  <p>ErrorMessage : <em>'DateTime' is a type but is used like a variable.</em></p>
  
  <p>This is related to 'out variables' changed in C# 7.0</p>
  
  <p>Unfortunately I can not use VS2017 (community) and <a href="https://www.youtube.com/watch?v=SMIfb0-U8sE" rel="nofollow noreferrer">THIS TUTORIAL</a> - not working (master branch is adapted to VS2017 now).</p>
  
  <p>Do you have an idea how to solve this problem?</p>
