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>
