using keyword for static class in C# 6.0

This feature lets the developers to invoke the static methods of the class without specifying the class name.

Assume that you have a class called Console which has a static method called WriteLine . In C# 5.0 and earlier version , you would end up specifying Console.WriteLine(“developerpublish.com C# tutorials”); as show below.

using System;
using System.Collections.Generic;
using System.Linq;

namespace MobileOSGeekApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("developerpublish.com C# tutorials");

            Console.ReadLine();
        }
    }
}

In C# 6.0 , you can simply include the class name with the using class Eg : using System.Console; and when using the method , invoke it without the class name as shown below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Console;
namespace MobileOSGeekApp
{
    class Program
    {
        static void Main(string[] args)
        {
            WriteLine("developerpublish.com C# tutorials");

            ReadLine();
        }
    }
}
