Question

I started to develop Asp.net Core web API with the VS code. But when I typing the code Intellisense/Suggestions not working properly. I saw in some resource on the internet while they are typing using Microsoft., EntityFrameworkCore showing as a suggestion. But In my case, it's not showing. In the OmniSharp log showing following error to me.

        Attempted to update project that is not loaded: c:Dotnet CoreNgWebApiNgWebApi.csproj

I re-installed the VS Code and C# , C# Extention to solve this problem, but it's still occurring. I think the reason was to not showing Intellisense/Suggestions the project is not properly loaded. Can anyone tell me how to avoid this error and how to solve Intellisense/Suggestions not showing the issue.

Answer 1

Solved (cross checked on Ubuntu 16.04 and CentOS 7):

In the VS Code menu, go into File / Preferences / Settings.

In the "Search settings" window, type omnisharp.path

Click on "Edit in settings.json" link.

Add (or edit) like this: "omnisharp.path": "latest"
