The following reasons make C# a widely used professional language:
 Modern, general-purpose programming language
 Object oriented.
 Component oriented.
 Easy to learn.
 Structured language.
 It produces efficient programs.
 It can be compiled on a variety of computer platforms.
 Part of .Net Framework.
