basically same issue with this: https://github.com/dotnet/vscode-csharp/issues/3640/#issue-577447944 but there's no solution found. I just started getting interested in this coding thing. Please help me.

[JoeRobich]

Looks like the extension is using the Roslyn LSP and VSCode was opened against a Unity script file. Looking at the installed extensions and it might help to install the Unity VSCode extension. See https://devblogs.microsoft.com/visualstudio/announcing-the-unity-extension-for-visual-studio-code/ for more details.

[gregnice0324]

I downloaded the Unity extension but it still doesn't work. Thank you for the help though.

[gregnice0324]

This is how my code looks vs how it should look like

This is the external tools settings in Unity if needed.

[JoeRobich]

The C# extension requires opening a folder containing either a .csproj or .sln file. It looks like Unity it opening the .cs file on its own.

I am not an expert on the Unity configuration but just wanted to be sure that you followed the steps outlined in https://code.visualstudio.com/docs/other/unity#_install. You have Unity 2021 or higher and the version of the 'Visual Studio Editor' Unity Package is 2.0.20 or higher.

Since this is a Unity issue, I believe the correct repo for this issue is https://github.com/microsoft/vscode-dotnettools/issues.
