Above answer from ikolim doesnt work as indicated by someone else too, there is no, Nuget: Install/Reference command. There is only Add Package! So the answer in the below link solved my problem. Manually editing the Myproject.csproj file.

Use the command dotnet add package to add a package reference to your project. For example: dotnet add package Newtonsoft.Json, which adds the package reference to the *.csproj project file:

<PackageReference Include="Newtonsoft.Json" Version="9.0.1" />

and now you can run the command dotnet restore to restores the dependencies of your project.

Reference: dotnet add package
