OmniSharp provides refactoring and AST support for the C# language for a variety of plugins written for popular text editors, including Vim, Emacs, Atom, Sublime Text, VS Code, and Brackets.

OmniSharp is a family of Open Source projects, each with one goal - To enable great .NET development in YOUR editor of choice. ~ omnisharp.net)

Background

OmniSharp Server, a project started by Jason Imison was written with the intention of providing refactoring and AST support for the C# language for Vim and later Emacs. Initially it was intended for own use, but grew in popularity and has had wide adoption in the game development community and developers writing C# on non Microsoft platforms.

Support has since been extended by the community to include Atom, Sublime Text and Brackets. OmniSharp has grown to be an umbrella term referring to the server and all plugins.

Today OmniSharp offers a lightweight alternative to traditional IDE's for developers wishing to write in their favourite editors. Offering code completion, formatting and other popular refactoring operations, syntax checking and easy code navigation.
