Missing "Microsoft.CodeAnalysis" in .net 3.1 install on Ubuntu-CodePudding

I have a .net project that runs in windows with VS code with no issues.

I am trying to run the same project in Ubuntu 20.04.2 with VS code. Run trying to run it with F5, I get the errors:

CSC : error CS8032: An instance of analyzer System.Text.Json.SourceGeneration.JsonSourceGenerator cannot be created from /home/one/.nuget/packages/system.text.json/6.0.6/analyzers/dotnet/roslyn3.11/cs/System.Text.Json.SourceGeneration.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.11.0.0, Culture=neutral, PublicKeyToken=****'.

I verified the files are on my system: roslyn3.11

It looks like "Microsoft.CodeAnalysis" was missing. So, I installed it with nuget in VS code. I added 'nuget: add package' in VS code to install 'Microsoft.CodeAnalaysis' version 3.11.0. I have verified it successfully lives on my system:

I still get the errors mentioned above.

CodePudding user response：

Install the latest NuGet packages of:

Microsoft.CodeAnalysis.Compilers
Microsoft.Net.Compilers

This will fix the issue.
