C# Console application

C# is one of the languages provided by Microsoft to work with .Net. This language encompasses a rich set of features, which allows the development of different types of applications. C# is an object-oriented programming language and resembles several aspects of the C++ Language. In this tutorial, we see how to develop our first application.

What is Console Application?

A console application, in the context of C#, is an application that takes input and displays output at a command-line console with access to three basic data streams: standard input, standard output, and standard error. A console application facilitates the reading and writing of characters from a console - either individually or as an entire line. It is the simplest form of a C# program and is typically invoked from the Windows command prompt. A console application usually exists in the form of a stand-alone executable file with minimal or no graphical user interface (GUI).
