This document provides an introduction and overview of the C# programming language. It discusses what C# is, its origins as part of Microsoft's .NET framework, and how to develop C# programs using Visual Studio. It also covers different versions of C# and the .NET frameworks it corresponds to. A simple "Hello World" C# program is shown as an example. The document compares C# and Java, noting differences in their platforms, technical features, and support for object-oriented programming. Finally, it lists some common applications of C# like desktop and web development.

3. WHAT IS C#?
C# is Microsoft’s premier language for .NET
development.
It leverages time-tested features with cuttingedge innovations and provides a highly
usable, efficient way to write programs for the
modern enterprise computing environment.
It is, by any measure, one of the most important
languages of the twenty-first century.

4. THE C# FAMILY TREE

5. TO DEVELOP C# PROGRAM..
Visual Studio
Can use csc.exe (for command line)
Or can use Visual Studio IDE
.NET Framework
To develop Desktop/Web application requires Visual Studio
IDE
Good amount of RAM and newer CPU for install VS IDE
Latest OS of Windows or Service Pack.

PLATFORM
Platform independent.
Platform depended.
Technicality
 Doesn’t Support Pointers for  Supports pointer
Developer
 It supports Operator Overloading
 Doesn’t Have Operator
 Does supports structure (struct)
Overloading apart from
Internal(+)
 Doesn’t have Structure
(struct)
COUPLED
Java and Windows are not
closely coupled.
C# and Windows are closely coupled.
ORM
Java has more ORM Support.
C# has LINQ (ORM)and etc..
Pure OOP
Partly OOP Language
Complete OOP Language

9. APPLICATIONS
Development of Desktop application.
Development in Web application.
Development of Operating System (Windows 8).

10. CONCLUSION
C#’s ability to work in a secure, mixed-language
environment is perhaps its most important componentoriented feature.
Like Java, C# is designed to produce portable code.
C# is not descended from Java.
