Cannot add NuGet packages

I am trying to use a NuGet package with dotnet-script. I have initialized a new script project as explained and added this into the main.csx file and restarted omnisharp. The using directive is always underlined with “Type or namespace could not be found”. I even do not see that any NuGet packages were downloaded.

#!/usr/bin/env dotnet-script
#r "nuget:GraphQlClientGenerator,0.7.3"
using GraphQLClientGenerator;

Here is the log

This is by design. dotnet-script will respect nuget.config to give you the ability to point to custom nuget feeds. Since NuGet 3.4 the nuget behavior is such that it will look in the project’s directory or “or any folder up to the drive root” to locate the config file https://docs.microsoft.com/en-us/nuget/consume-packages/configuring-nuget-behavior

I have added the official package source and it works. Not sure if above are still bugs to look at or if we can close this.

<packageSources>
    <add key="HangfirePro" value="..." />
    <add key="MyGet" value="..." />
    <add key="NuGet official package source" value="https://nuget.org/api/v2/" />
