I'm trying to test some c#7 features as outlined in this blog.
https://joshvarty.wordpress.com/2016/02/10/l-quick-tip-how-to-test-out-c-7-features-with-roslyn/
I've followed the steps many times and I've got the projects to build and open a new instance of VS. Once I open the instance, I'm then creating a new console project from the file menu. When I attempt to use the Tuples I get the following error. Error CS0518 Predefined type 'System.ValueTuple`2' is not defined or imported
I'm not sure if I'm doing something wrong? I'm feeling like there's one tweak that's missing.
