Omnisharp-vscode: Intellisense not working in C# extension of VS Code

[sshankhdhar]

Intellisense not working in C# extension of VS Code.
Every time I'll have to restart the VS Code and wait.
Sometimes Intellisense works and sometimes not.

@sshankhdhar
Could you please provide a log from the Output window for Omnisharp Log target from your VSCode? It would help tremendously.
Thanks!

@benitazz It appears your project is targeting .NET Core 3.1 but you are trying to run against .NET Core 2.1. Try running dotnet --info and installing the .NET Core 3.1 SDK if it isn't already.

[JoeRobich]

@sshankhdhar I see that OmniSharp is trying to run against the minimal MSBuild that we deploy with. This MSBuild wouldn't necessarily support all project types.

You can try installing the VS2019 Build Tools from https://visualstudio.microsoft.com/downloads/. Expand 'Tools for Visual Studio 2019' and download 'Build Tools for Visual Studio 2019'

[benitazz]

I was able to resolve my issue by installing the correct SDK of .net core

[cartermp]

@sshankhdhar Thanks for filing this issue. Are you still seeing this problem? If so, could you share the following information:

• The kind of project(s) you're attempting to use (.NET Framework, .NET Core, how many projects, etc.)
• Any sharable repository

Thanks!

Closing out as no additional info was added.
