How to set up omnisharp with roslynator

[tXJtqlb3bbeKD1yW8SV7]

I couldn't get omnisharp to work with https://github.com/JosefPihrt/Roslynator as the wiki says you can. Do I have to put a path to some .dll file that is inside the nuget package in the omnisharp.json?

@tXJtqlb3bbeKD1yW8SV7, If you are using VS Code, then there is a Roslynator extension you can install. Otherwise, I think you can use these instructions and it will work even if you aren't using VS Code.

No such luck.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
