  Introduction
  C# is a Sharp C
  C#, pronounced c sharp, is a computer language used to give
  instructions that tell the computer what to do, how to do it, and when to do it.
  This is a universal language that is used on many operating systems, including
  Microsoft Windows. C# is one of the languages used in the Microsoft .NET
  Framework. The Microsoft .NET Framework is a library of objects that create or
  draw things on the computer.
  Console Applications
  The C# language is used to create applications that display
  on a black window referred to as the DOS prompt or DOS window. Those are the
  types of applications we will create in our lessons.
  To study the C# language, we will use Microsoft Visual C#
  2008 Express Edition or Microsoft Visual C# 2008 Professional. To get Microsoft
  Visual C# 2008 Express Edition, you can download it free from the
  Microsoft web site. After
  downloading it, you can install it.
  To launch Microsoft Visual C# 2008 Express Edition, you can
  click Start -> (All) Programs -> Microsoft Visual C# 2008 Expression Edition:
  To launch Microsoft Visual C# 2008 Professional, you can
  click Start -> (All) Programs -> Microsoft Visual Studio 2008. To create the
  type of applications we will study in our lessons, on the main menu, you can
  click File -> New Project... In the Templates section of the New Project dialog
  box, you can click Console Application, accept the default name or change it:
  After clicking OK, a skeleton code would be created for you.
  Right now, we will not review every part of the code. Everything will be
  introduced and explained as we move on.
  Writing Code
  The programs# 2008
  includes a text editor referred to as the Code Editor. This is the window that
  displays when you have just created a console application. Besides the Code
  Editor, the integrated development interface (IDE) of the Microsoft Visual C#
  2008 is made of.Linq;
  // using System.Text;
  /*
  namespace GeorgetownCleaningServices1
  {*/
  class Program
  {
  static void Main(/* string[] args */)
  {
  }
  }
  //}. 2008 (any edition) is
  installed, it creates a folder named Visual Studio 2008 in your My Documents
  folder. The My Documents folder is called your personal drive or your personal
  directory. Inside of the Visual Studio 2008... the My Documents\Visual
  Studio.
