  C# is a modern, object-oriented programming language developed by Microsoft
  as part of the .NET platform. It is used for building Windows applications,
  web services, games (via Unity), and enterprise software, offering strong
  typing, garbage collection, and rich framework support. The C# language is
  defined by a standardized specification and implemented by the Roslyn
  compiler, with packages distributed via NuGet and running on the .NET
  runtime.
