I try to open a Unity3D project with VSCode under Linux (Ubuntu 18.10). The omnisharp extension doesn’t load the project, saying assemblies were not found.
It may seems very stupide, but i’m not really used to .Net yet, and i have been stuck with this error for quite some days now. I have been trying re-installing dotnet (even using the snap package), mono, vscode and the omnisharp extension.
So any help is welcome ! 🙂

The reference assemblies for framework ".NETFramework,Version=v4.7.1" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

Answer
I had the same issue but on OSX. Installing latest version of Mono cleared up the missing .net v4.7.1 framework references.
I installed Mono V5.18.0 from https://www.mono-project.com/download/stable
