OmniSharp is a .NET development platform based on Roslyn workspaces. It provides project dependencies and C# language services to various IDEs and plugins.
OmniSharp is built with the .NET Core SDK on Windows and Mono on OSX/Linux. It targets the net472 target framework. For platforms other than Windows, OmniSharp ships with an embedded Mono which is based on version 6.12.0, includes MSBuild 16.8.0 and is provisioned during the build script. If Mono is globally installed on the system, OmniSharp will prefer it over the embedded version, however version >=6.4.0 is required (the lowest version with at least MSBuild 16.3.0).
For Arch Linux users, you need package mono-msbuild (>= 16.3).
In addition, if you need the HTTP interface and you want to run on Linux, you'll also need to make sure that you have libuv installed. See also OmniSharp#1202 (comment) .
See our change log for all of the updates.
OmniSharp ships in two flavors:
- Stdio server
- HTTP server
When using OmniSharp with an editor extension (e.g. VIM, Emacs, VS Code), the extension will download or bundle OmniSharp automatically. If you wish to download OmniSharp manually though, follow the steps below.
Stable releases are published using GitHub releases. Each release contains a set of binaries for various operating systems and processing architectures.
Pre-release versions are available in Azure Blob Storage, they can be viewed using the following URL https://roslynomnisharp.blob.core.windows.net/releases?restype=container&comp=list&prefix={version}, where the {version} placeholder can be found in the changelog. For example, all 1.37.x versions (including all betas and prereleases such as 1.37.4-beta.5) can be viewed using https://roslynomnisharp.blob.core.windows.net/releases?restype=container&comp=list&prefix=1.37. Please note that the listing is limited to 5000 entries.
Every merge to master is automatically published to this feed and individual release is then available using the following URL convention:
https://roslynomnisharp.blob.core.windows.net/releases/{version}/{packagename}-{os/arch}.{ext}
- Version is auto incremented and is visible in the travis or appveyor build output
- Package Name would be either
omnisharporomnisharp.http os/archwill be one of the following:win-x64win-x86win-arm64linux-x64linux-x86linux-musl-x64linux-arm64linux-musl-arm64osxmono(Requires global mono installed)
- Extensions are archive specific, windows will be
zipand all others will betar.gz.
On Windows:
> ./build.ps1
On Linux / Unix:
$ ./build.sh
You can find the output under artifacts/publish/OmniSharp/<runtime id>/<target framework>/.
The executable is either OmniSharp.exe or OmniSharp.
For more details, see Build.
Add the following setting to your User Settings.
{
"omnisharp.path": "<Path to the omnisharp executable>"
}The above option can also be set to:
- "latest" - To consume the latest build from the master branch
- A specific version number like
1.29.2-beta.60
In order to be able to attach a debugger, add the following setting to your User or Workspace settings:
{
"omnisharp.waitForDebugger": true
}This will print the OmniSharp process ID in the VS Code OmniSharp output panel and pause the start of the server until a debugger is attached to this process. This is equivalent to launching OmniSharp from a command line with the --debug flag.
OmniSharp provides a rich set of hierarchical configuration options, controlled via startup arguments, environment variables and omnisharp.json file. For more details please visit the Configuration Options section of the wiki.
