                  OVERVIEW 
                   
                           C#  is  a  modern,  general-purpose,  object-oriented  programming  language  developed  by 
                  Microsoft and approved by Ecma and ISO.C# was developed by Anders Hejlsberg and his team during 
                  the development of .Net Framework. 
                           C# is designed for Common Language Infrastructure (CLI), which consists of the executable code 
                  and  runtime  environment  that  allows  use  of  various  high-level  languages  to  be  used  on  different 
                  computer platforms and architectures. 
                  The following reasons make C# a widely used professional language: 
                                    Modern, general-purpose programming language. 
                                    Object oriented. 
                                    Component oriented. 
                                    Easy to learn. 
                                    Structured language. 
                                    It produces efficient programs. 
                                    It can be compiled on a variety of computer platforms. 
                                    Part of .Net Framework. 
                  Getting started 
                   
                  Creating a new visual studio C# project: 
                  Once  Visual  Studio  is  running  the  first  step  is  to  create  a  new  project.  Do  this  by  selecting New 
                  Project from the File menu. This will cause the New Project window to appear containing a range of 
                  different types of project. For the purposes of this tutorial we will be developing a Windows Forms 
                  Application so make sure that this option is selected. 
                  CREATING NEW PROJECT 
                  The first thing you do when you want to create a new application is to create a NEW PROJECT. 
                  This can be done from start page.
