Explanation

Most C# applications start with a section of using directives. The section lists the namespaces that the application will be using regularly, and saves the programmer from mentioning a fully qualified name every time a method contained within the namespaces is used. For instance, by including the line: At the start of a program, the programmer can use the following code: Console.WriteLine("Welcome, World!"); Rather than using the following code: System.Console.WriteLine("Welcome, World!");
