When I start editing a C# file I get this warning message
Some projects have trouble loading. Please review the output for more details.
I check the output and this is what I find

It looks like you have Mono installed which contains a MSBuild lower than 16.8.0 which is the minimum supported by the configured .NET Core Sdk.
Try updating Mono to the latest stable or preview version to enable better .NET Core Sdk support.

This project targets .NET version that requires reference assemblies that do not ship with OmniSharp out of the box (e.g. .NET Framework). The most common solution is to make sure Mono is installed on your machine (https://mono-project.com/download/) and that OmniSharp is started with that Mono installation (e.g. 'omnisharp.useGlobalMono':'always' in C# Extension for VS Code).

I checked the solution they wrote solution is to make sure Mono is installed on your machine (https://mono-project.com/download/) and that OmniSharp is started with that Mono installation (e.g. 'omnisharp.useGlobalMono':'always' in C# Extension for VS Code). And it fixed the problem, but the next day the problem occurred again!
Here is what I added in my settings.json
"omnisharp.path": "latest",
"omnisharp.useGlobalMono": "always"
The extensions I have for C# are C# extension and Roslynator.
Is there something missing to completely set up visual studio code for C#? I'm completely new to C# and I would really appreciate any help to get the same smooth feeling as in other programming languages like JavaScript or Golang
Note: I use Mac, but does this make any difference?
Fix that by theses steps:
