New features in C# 6.0

You can get the new features from C# 6.0 here

I try to put as many new features as possible in a single program.

class Program


    static void Main(string[] args)


        Customer customers = new Customer();

        //Extension methods

        var range = Range(5, 17);

        var even = range.Where(i => i % 2 == 0); // Ok


        //Null-conditional operators

        int? length = customers?.Length;

        //String interpolation

        var s = “\{customers.Name} is \{customers.Age} year{s} old”;

        //nameof expressions


        //Index initializers

        var numbers = new Dictionary<int, string> {[7] = “seven”,[9] = “nine”,[13] = “thirteen” };




    public class Customer


        //Initializers for auto-properties

        public string First { get; set; } = “Jane”;

        public string Last { get; set; } = “Doe”;

        public int Length { get; set; }

        public string Name { get; }

        public int Age { get; set; }

        public Customer() {  }

        public Customer(string first, string last) { Name = first + ” “ + last; }

        //Expression bodies on method-like members

        public void Print() => Console.WriteLine(First + ” “ + Last);
