@mm75: what Linux distro are you running?

@DustinCampbell
Plataform: Ubuntu 15.10 wily
Desktop: Mate

Ubuntu 15.10? OmniSharp should only install and run on 14 or 16. I'll install that distro and see why (https://github.com/OmniSharp/omnisharp-vscode/blob/master/src/platform.ts#L61-L69) is allowing 15.10.

Now that I step through the code, I see why it isn't working. It's a rookie mistake: case fall through. 😄 Since, the "ubuntu" case only checks for versions 14 or 16, version 15 is unhandled. However, there's no break statement, so it just falls through to the "centos" case.

Unfortunately, Ubuntu 15.10 is not a supported Linux distro today. You can get things working with the Mono version of OmniSharp by using the following steps though:

1. Install Mono
2. Download and untar the mono flavor of OmniSharp here.
3. In Visual Studio Code, select Preferences -> User Settings.
4. In settings.json, add the following:

"csharp.omnisharp": "/path/to/the/OmniSharp/executable/you/just/untarred",
"csharp.omnisharpUsesMono": true

Note: In the next release of the C# Extension, we're changing these values to:

"omnisharp.path": "/path/to/the/OmniSharp/executable/you/just/untarred",
"omnisharp.usesMono": true

Note: We intend to make the process of acquiring the mono version of OmniSharp easier on any Linux distro. #593
