title: How to run Roslyn instead csc.exe from command line?
body: <p>After installing VS 2015, running csc.exe from command line causes this message to be displayed to console:</p>
  
  <blockquote>
    <p>This compiler is provided as part of the Microsoft (R) .NET Framework,
    but only supports language versions up to C# 5, which is no longer the
    latest version. For compilers that support newer versions of the C#
    programming language, see

  <p>The link redirects to Roslyn's repository at GitHub.<br>
  So, is the a way to run "compilers that support newer versions" (Roslyn) from command line?</p>
