C# Introduction
C# (C Sharp)
Definition - What does C# (C Sharp) mean?
C# is a general object-oriented programming (OOP) language for networking and Web development. C# is specified as a common language infrastructure (CLI) language.
In January 1999, Dutch software engineer Anders Hejlsberg formed a team to develop C# as a complement to Microsoft’s NET framework. Initially, C# was developed as C-Like Object Oriented Language (Cool). The actual name was changed to avert potential trademark issues. In January 2000, NET was released as C#. Its NET framework promotes multiple Web technologies.
The term is sometimes spelled as C Sharp or C-Sharp.
What is Console Application?
A console application is an application that runs in a console window same as a C and C++ program.
It doesn’t have any graphical user interface. Console Applications will have character based interface.
It doesn’t have any graphical user interface. Console Applications will have character based interface.
