The reference assemblies for framework ".NETFramework,Version=v3.5" 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.OmniSharp failed to start in VSCode terminal when I open project for Unity.
Reinstalling or Updating Mono and .Net core was failed.
Well, OmniSharp use Mono compiler not .Net core things. So it won't be problem of .Net core.
May be terminal on VSCode has problem, like messed bash profile.
Yes. bash history showed that when I overwrite bash profile I just forget to adding $PATH on the end, ignoring default path.
I just didn't notice cause new packages on new added path works well. Fuck myself (on yesterday).
Adding $PATH, all fixed.
