The introduction of the Microsoft .NET framework at the Professional Developers Conference in
July 2000 also saw Microsoft introduce a new programming language called C# (pronounced
“see-sharp”). The name was inspired by musical notation where a # sharp symbol indicates that a
written note should be a semitone higher in pitch. This notion is similar to the naming of the C++
programming language where the ++ symbol indicates that a written value should be incremented
by 1.
