Answer 1

Yes! You need to consume the NuGet.Configuration package available at https://www.nuget.org/packages/NuGet.Configuration/4.6.2.

Then you can use the following code -

using NuGet.Configuration;
using System;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // basic implementation of nuget.config in code
            var setting = Settings.LoadSpecificSettings(@"f:\root", "nuget.config");

            // get sources 
            var packageSourceProvider = new PackageSourceProvider(setting);
            var sources = packageSourceProvider.LoadPackageSources();

            foreach(var source in sources)
            {
                Console.WriteLine($"{source.Name}: {source.SourceUri}");
            }
        }
    }
}

This will generate the following output -

NuGet.org: https://api.nuget.org/v3/index.json

Sample config file used (lets say at path f:\root\nuget.config)-

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="NuGet.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>
