How to get the dependencies of a NuGet package from private NuGet feed?

I have tried this for load a package using NuGet.Core. How shall I proceed further on this? I need to get the list of dependency packages of the package in a list from public/private feed using C#.

string packageID = "EntityFramework";IPackageRepository repo = PackageRepositoryFactory.Default.CreateRepository("https://packages.nuget.org/api/v2");var package = repo.FindPackage(packageID);
