These lessons are designed to keep you engaged with the process of learning C# basics. Our main focus will be on learning C# basics.

Lesson 1 Introduction and version history

C# is a simple & powerful object-oriented programming language developed by Microsoft and approved by European Computer Manufacturers Association (ECMA) and International Standards Organization (ISO). C# can be used to create various types of applications, such as web, windows, console applications or other types of applications

C# was developed by Anders Hejlsberg and his team during the development of .Net Framework.

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

So, how did the C# language appear? Let's see below:

1. C language was created by Dennis MacAlistair Ritchie, an American computer scientist, in 1972.

2.In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on "C with Classes", the predecessor to C++. In 1983, "C with Classes" was renamed to "C++"

3.James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. Sun Microsystems released the first public implementation as Java 1.0 in 1996.

4. In January 1999, Anders Hejlsberg formed a team to build a new language at the time called Cool, which stood for "C-like Object Oriented Language". Microsoft had considered keeping the name "Cool" as the final name of the language, but chose not to do so for trademark reasons. By the time the .NET project was publicly announced at the July 2000 Professional Developers Conference, the language had been renamed C#, and the class libraries and ASP.NET runtime had been ported to C#.C# has evolved much since its first release in 2002. C# was introduced with .NET Framework 1.0 and the current version of C# is 7.0.
