OmniSharp.MSBuild.ProjectManager Attempted to update project that is not loaded:

问题

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 Core\NgWebApi\NgWebApi.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.

回答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"

回答2:

Solved: Check if Visual Studio Build Packages is installed, if so uninstall it. As soon as uninstall VScode will work fine and intellisense feature will be back. Good luck!

回答3:

I solved this by upgrading my Mono project version https://www.mono-project.com/

回答4:

To solve this I did several things. First of all, I downgrade OmniSharp version by installing their beta version. download the .vsix file for that release to my machine. Used the following steps to install the .vsix into Visual Studio Code.

Open Visual Studio Code and select View->Extensions from the menu to display the Extensions pane
By clicking the ... at the top-right corner of the Extensions pane and select "Install from VSIX..." on the menu.
Located the .vsix the file I downloaded and Opened it
Then restart vs code

But the problem still occurred, so then I downgraded the .Net core SDK v2.2.202 version to 2.1.202 and the problem is solved.
