 **An environment for development** \(Integrated Development Environment – **IDE**\) is an union of traditional tools for development of software applications. In the development environment we write code, compile and execute the programs. Development environments integrate in them **a text editor** for writing code, **a programming language**, **a compiler or an interpreter** and **a runtime environment** for executing programs, **a debugger** for tracking the program and seeking out errors, **tools for user interface design** and other tools and add-ons.
 
-**Environments for development** are convenient, because they integrate everything necessary for the development of the program, without the need to exit the environment. If we don't use an environment for development, we will have to write the code in a text editor, to compile it with a command in the console, to run it with another command in the console and to write more additional commands when needed, which is very time consuming. That is why most of the programmers use an IDE in their everyday work.

 For programming with **the C\# language** the most commonly used IDE is **Visual Studio**, which is developed and distributed freely by Microsoft and can be downloaded from: [https://www.visualstudio.com/downloads/](https://www.visualstudio.com/downloads/).

 This command is very typical in programming: we say a given **object** should be found \(in this case the console\) and some **action** should be executed upon it \(in this case it is printing something that is given inside the brackets\). More technically explained, we call the method `WriteLine(…)` from the class `Console` and give as a parameter to it a text literal `"Hello C#"`.
