What is C# programming language

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 C# programming language

C# is used for

  • Mobile applications
  • Desktop applications
  • Web applications
  • Web services
  • Web sites
  • Games
  • VR
  • Database applications

Why Use C#?

  • It is one of the most popular programming language in the world
  • It is easy to learn and simple to use
  • It has a huge community support
  • C# is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs.
  • As C# is close to C, C++ and Java, it makes it easy for programmers to switch to C# or vice versa


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 .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 language. It has strong resemblance with Java, it has numerous strong programming features that make it endearing to a number of programmers worldwide.

Following is the list of 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 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, we will use Visual Studio Community, which is free to download from https://visualstudio.microsoft.com/vs/community/.

Applications written in C# use the .NET Framework, so it makes sense to use Visual Studio, as the program, the framework, and the language, are all created by Microsoft.

C# Install

Once the Visual Studio Installer is downloaded and installed, choose the .NET workload and click on the Modify/Install button:

After the installation is complete, click on the Launch button to get started with Visual Studio.

On the start window, choose Create a new project:

Then click on the “Install more tools and features” button:

Choose “Console App (.NET Core)” from the list and click on the Next button:

Enter a name for your project, and click on the Create button:

Visual Studio will automatically generate some code for your project:

The code should look something like this:
