C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its. NET initiative led by Anders Hejlsberg. This tutorial will teach you basic C# programming and will also take you through various advanced concepts related to the C# programming language. You must enroll yourself in Bootcamp coding courses provided by Eduriefy

C# is a modern,all general-purpose, object-oriented programming language developed by Microsoft and approved by European Computer Manufacturers Association (ECMA) and International Standards Organization (ISO). C# was developed by Anders Hejlsberg and his team during the development of the .Net Framework.

C# is designed for Common Language Infrastructure (CLI), which consists of the executable code and runtime environment that allows the use of various high-level languages on different computer platforms and architectures.

The following reasons make C# a widely used professional language −

  • It is a modern, general-purpose programming language
  • It is object-oriented.
  • It is component-oriented.
  • It is easy to learn.
  • It is a structured language.
  • It produces efficient programs.
  • It can be compiled on a variety of computer platforms.
  • It is a part of the . Net Framework.

Strong Programming Features of C#

  • Although C# constructs closely follow traditional high-level languages, C and C++ and being an object-oriented programming languages. It has a strong resemblance with Java, it has numerous strong programming features that make it endearing to several programmers worldwide. Coding courses are gaining importance over the years and in this scenario, you must visit the Edureify website to have access to the best courses.

Following is the list of a few important features of C# −

  • Boolean Conditions
  • Automatic Garbage Collection
  • Standard Library
  • Assembly Versioning
  • Properties and Events
  • Delegates and Events Management
  • Easy-to-use Generics
  • Indexers
  • Conditional Compilation
  • Simple Multithreading
  • LINQ and Lambda Expressions
  • Integration with Windows

The . Net Framework

The. Net framework is a revolutionary platform that helps you to write the following types of applications −

  • Windows applications
  • Web applications
  • Web services

The Net. framework applications are multi-platform applications. The framework has been designed in such a way that it can be used in any of the following languages: C#, C++, Visual Basic, Jscript, COBOL, etc. All these languages can access the framework as well as communicate with each other.

The Net framework consists of an enormous library of codes used by the client languages such as C#. Following are some of the components of the .Net framework −

  • Common Language Runtime (CLR)
  • The Net Framework Class Library
  • Common Language Specification
  • Common Type System
  • Metadata and Assemblies
  • Windows Forms
  • ASP Net and ASP Net AJAX
  • ADO. Net
  • Windows Workflow Foundation (WF)
  • Windows Presentation Foundation
  • Windows Communication Foundation (WCF)
  • LINQ

Integrated Development Environment (IDE) for C#

Microsoft provides the following development tools for C# programming −

  • Visual Studio 2010 (VS)
  • Visual C# 2010 Express (VCE)
  • Visual Web Developer

The last two are freely available from Microsoft’s official website. Using these tools, you can write all kinds of C# programs from simple command-line applications to more complex applications. You can also write C# source code files using a basic text editor, like Notepad, and compile the code into assemblies using the command-line compiler, which is again a part of the NET Framework.

Visual C# Express and Visual Web Developer Express editions are trimmed down versions of Visual Studio and have the same appearance. They retain most features of Visual Studio. In this tutorial, we have used Visual C# 2010 Express.

You can download it from Microsoft Visual Studio. It gets installed automatically on your machine.

Note: You need an active internet connection for installing the express edition.

Writing C# Programs on Linux or Mac OS

Although the.NET Framework runs on the Windows operating system, some alternative versions work on other operating systems. Mono is an open-source version of the .NET Framework which includes a C# compiler and runs on several operating systems, including various flavors of Linux and Mac OS. 

The stated purpose of Mono is not only to be able to run Microsoft .NET applications cross-platform but also to bring better development tools for Linux developers. Mono can be run on many operating systems including Android, BSD, iOS, Linux, OS X, Windows, Solaris, and UNIX.

C# is an object-oriented programming language. In Object-Oriented Programming methodology, a program consists of various objects that interact with each other user actions. The actions that an object may take are called methods. Objects of the same kind are said to have the same type or, are said to be in the same class.

For example, let us consider a Rectangle object. It has attributes such as length and width. Depending upon the design, it may need ways for accepting the values of these attributes, calculating the area, and displaying details.


Let us look at the implementation of a Rectangle class and discuss C# basic syntax −

using System;

namespace Rectangle Application {

   class Rectangle {    

      // member variables

      double length;

      double width;

     public void Accept details() {

         length = 4.5;    

         width = 3.5;


      public double Get Area() {

         return length * width; 


      public void Display() {

         Console. WriteLine(“Length: {0}”, length);

         Console. Write Line(“Width: {0}”, width);

         Console. Write Line(“Area: {0}”, Get Area());



   class Execute Rectangle {

      static void Main(string[] args) {

         Rectangle r = new Rectangle();

         r. Accept details();

         r. Display();

         Console. Read Line(); 





Length: 4.5

Width: 3.5

Area: 15.75

Frequently Asked Questions (FAQs)

Question:- What is C# used for?

Answer:- C# is often used to develop professional, dynamic websites on the. NET platform, or open-source software. So, even if you’re not a fan of the Microsoft architecture, you can still use C# to create a fully-functional website.

Question:- Is C++ different than C#?

Answer:- C++ is known as an intermediate-level language that adds object-oriented features to its base C, whereas C# is a high-level language. C++ compiles programs to Machine Codes, and C# compiles programs to Common Language Runtime or CLR.

Question:- Is C# for beginners?

Answer:- C# programming is very much based on C and C++ programming languages, so if you have a basic understanding of C or C++ programming, then it will be fun to learn C#.

Question:- Where do I start with C#?

Answer:- C# IDE. The easiest way to get started with C# is to use an IDE. An IDE (Integrated Development Environment) is used to edit and compile code. In our tutorial at Edureify, we will use Visual Studio Community.
