title: How can I enable all features of C# 7 in Visual Studio 2017 project?
body: <p>After Visual Studio 2017 was released I wanted to try to create simple console project with new C# 7 features. I expected that I simply download new Visual Studio 2017, then create new console project and can use new C# 7 features. But I can't. </p>
  
  <p>I can use some features, like Tuples if I install <a href="https://github.com/dotnet/roslyn/blob/master/docs/features/tuples.md" rel="noreferrer">NuGet package System.ValueTuple</a>.</p>
  
  <p>But for other features, I don't know what I need to do. For example <a href="https://github.com/dotnet/roslyn/issues/7169" rel="noreferrer">this NuGet issue</a>. </p>
  
  <p>Do I need to do all this dirty install now? Or I can enable c# 7 features in a more simple way?</p>
