With the latest omnisharp

[Jeeth7]

Hi I am using ubuntu and vscode. With the latest omnisharp update I am frequently getting the error on roslynator as below.
Did I miss any configuration setups.
Currently I uninstall Roslynator and then uninstall omnisharp and install omnisharp and install Roslynator for fix this.

Hi, After installing the .net 5.0 this issue got resolved.
I am not sure if this is the correct fix for this issue. I already had .net 3.0 and .net 6.0
