Created on 20 Aug 2019 · 1Comment · Source: OmniSharp/omnisharp-vscode

Issue Description

Cannot run Unity projects as the the reference assemblies for framework ".NETFramework,Version=v4.7.1" were not found on Mac OSX.

I have the latest .net core and mono versions installed. Additionally if I force mono with "omnisharp.useGlobalMono": "true" I get an error [ERROR] Error: Cannot start OmniSharp because Mono version >=5.8.1 is required.

mono -V
Mono JIT compiler version 6.0.0.319 (2019-02/52203786470 Thu Aug 1 07:35:17 EDT 2019)
