Having the lambda expression for the function members is one of the cool feature specially for simple and straight forward methods.

In the earlier versions of C# , lambda expression was one of the option when an delegate was expected as input .

For example ,

using System;
using System.Linq;
namespace MobileOSGeekApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Func<int, int,int> AddNumber = (a, b) => a + b;
            Console.WriteLine(AddNumber(1,2));
            Console.ReadLine();
        }
    }
}

C# 6.0 allows the developers to use lambda expression as the body of the function member.

Lambda Expression for Function Members in C# 6.0

Code snippet demonstrating the usage of the Lambda expression for the function members in C# 6.0

using System;
using System.Linq;

namespace MobileOSGeekApp
{
    class Program
    {
    // Lambda expression used in function member
        public static int AddNumber(int a, int b) => a + b;
        static void Main(string[] args)
        {
            Console.WriteLine(AddNumber(1,2));
            Console.ReadLine();
        }
    }
