Console C#.Net Tutorial
Anders Hejlsberg
Founder of C#
C# is pronounced as "C-Sharp". The name 'C#' was inspired by the musical notation where a sharp indicates that the written note should be made a semitone higher in pitch. This is similar to the language name of C++, where '++' indicates that a variable should be incremented by 1 after being evaluated. The sharp symbol also resembles a group of four '+' symbols, further implying that the language is an increment of C++.
