C# 6 Modified & Removed Features

Using static classes as directive

Earlier Releases

  1. using System.Console;   
  2. using System.Convert;    
  • In the previous release we do not need to use the “static” keyword for using static classes as directive.
  • In previous version we can only use static classes and namespaces in as directive.

Current Release (VS 2015)

  1. using static System.Console;   
  2. using static System.Convert;    
  1. Now we need add static keyword to use static classes as directive.
  2. In previous release apart from namespace we can use static classes. But in current release (VS 2015) using static keyword we can include static classes & non static classes, too.
