This is a mode for editing C# in emacs. It’s based on cc-mode, v5.30.3 and above.

Travis-CI build-page. Build-status:

• font-lock and indent of C# syntax including:
  • all c# keywords and major syntax
  • attributes that decorate methods, classes, fields, properties
  • enum types
  • #if/#endif #region/#endregion
  • instance initializers
  • anonymous functions and methods
  • verbatim literal strings (those that begin with @)
  • generics
• automagic code-doc generation when you type three slashes.
• intelligent insertion of matched pairs of curly braces.
• imenu indexing of C# source, for easy menu-based navigation.
• compilation-mode support for msbuild, devenv and xbuild.

This package is currently available on MELPA & Marmalade. Install using M-x package-install<RET>csharp-mode.

Once installed the package should be automatically used for files with a ‘.cs’-extension.

Note: This package is also available on MELPA-stable for those who don’t want or need bleeding edge development-versions.

For a better experience you may want to enable electric-pair-mode when editing C#-files. To do so, add the following to your .emacs-file:

(defun my-csharp-mode-hook ()
  ;; enable the stuff you want for C# here
  (electric-pair-mode 1))
(add-hook 'csharp-mode-hook 'my-csharp-mode-hook)

For further mode-specific customization, M-x customize-group RET csharp RET will show available settings with documentation. For configuring cc-mode settings (which csharp-mode derives from) see the cc-mode manual.

For more advanced and IDE-like functionality we recommend using csharp-mode together with Omnisharp-Emacs.

This repo is a fork of the code originally developed by Dylan R. E. Moonfire and further maintained by Dino Chiesa as hosted on Google code.

The original csharp-mode repo contained lots of different code for lots of different purposes, some finished, some not, some experimental, some not. Basiaclly things like ASPX-mode, TFS-mode, code completion backends, etc.

All this original code can still be found in the extras-branch, but we have decided to go for a more focused approach and to throw out all dead or unused code, code we wont be maintaining.

The goal: That what we package in csharp-mode actually works and works well.

The original project was licensed under GPL v2, so this one is too.
