Description Jonathan Chambers 2016-07-07 21:27:14 UTC
String interpolation is available even when langversion is set to a version < 6.

The following code compiles just fine with 'mcs -langversion:4':

using System;

public class Program
{
	public static void Main()
	{
		// the following line does produces a compiler error with -langversion:4
		//var s = nameof(Main);
		// the following line does not produce a compiler error with -langversion:4
		Console.WriteLine($"I should not compile");
	}
}
