C# for Visual Studio Code (powered by OmniSharp)

Master	Release

Welcome to the C# extension for Visual Studio Code! This preview provides the following features inside VS Code:

• Lightweight development tools for .NET Core.
• Great C# editing support, including Syntax Highlighting, IntelliSense, Go to Definition, Find All References, etc.
• Debugging support for .NET Core (CoreCLR). NOTE: Mono and Desktop CLR debugging is not supported.
• Support for project.json and csproj projects on Windows, macOS and Linux.

The C# extension is powered by OmniSharp.

• Video Tutorial compiling with .NET Core

What's New in 1.13.0

• Support for Cake files. (https://cakebuild.net/)
• The language service now runs on Mono >= 5.2.0 when it is globally installed on macOS or Linux, resulting faster project load times.
• If debugging is started when a launch.json is not present, picking ".NET Core" generates a launch.json dynamically that can correctly launch a .NET Core app without any additional changes.
• Better reliability loading projects when Visual Studio 2017 (Windows) or Mono >= 5.2.0 (macOS/Linux) is installed.
• Fixed issues with non-C# projects (such as F#) being treated as C# projects.
• Addressed bugs when renaming files.
• New options for controlling the display of the references and test CodeLens:
  • csharp.referencesCodeLens.enabled
  • csharp.testsCodeLens.enabled
• Fixed problems with running/debugging xUnit 2.3.0 or NUnit tests.
• Many other bug fixes!

See our change log for all of the updates.

Supported Operating Systems for Debugging

• Currently, the C# debugger officially supports the following operating systems:

  • Windows (64-bit only)
  • macOS 10.12 (Sierra) and newer
  • Ubuntu 14.04+ (and distros based on it)
  • Debian 8.7+
  • Red Hat Enterprise Linux (RHEL) / CentOS / Oracle Linux 7.3+
  • Fedora 23 / 24 / 25
  • OpenSUSE 42.2+

This list is currently the same as the x64 .NET Core 2.0 operating systems (see .NET Core list). Note that other Linux distributions will likely work as well as long as they include glibc, OpenSSL 1.0, and libunwind.
