I am not a language service guy, but I am fairly certain the issue is that the new OmniSharp requires a newer mono. So if you can, try upgrading your globally installed mono to 5.8.1 (or newer). There is a PR out currently to try and detect this.

If that doesn't help, someone who knows more about OmniSharp can hopefully help in the morning.

I uninstalled mono 5.4.1.6 (via brew) and installed latest 5.12 from mono-project. Error resolved, thank you @gregg-miskelly!

DustinCampbell commented 6 years ago

@anfomin / @dbogatov : There was a subtle bug in Mono that was exposed by Roslyn 2.7.0 that has since been fixed. Unfortunately, we forgot to update the minimum Mono version requirement in C# for VS Code. We should have a new release out shortly that addresses that problem.
