I have create one console application with some new features in vs2015.Here I have used
1. Using static:( Accessible all static members)
Example
  1. using static System.Math;
2. Expression bodies on method-like members
Please find the below code:
  1. using System;
  2. //Using static
  3. using static System.Math;
  4. namespace ConsoleApplication1 {
  5. class Program {
  6. static void Main(string[] args) {
  7. Program obj = new Program();
  8. //Console.WriteLine(obj.GetSqrt(3));
  9. Console.WriteLine(obj.GetString());
  10. Console.ReadLine();
  11. }
  12. public string X = "Hi";
  13. public string Y = "How";
  14. public Int32 FastValue = 4;
  15. public Int32 Secondvalue = 5;
  16. //Expression bodies on method-like members
  17. public double GetTotalValu() = > Sqrt(FastValue + Secondvalue * FastValue + Secondvalue);
  18. public double GetSqrt(int x) = > Sqrt(x);
  19. //String.format=$
  20. public string GetString() = > $ "({X},{Y})";
  21. }
  22. }


Output:
