如何在.NET Core中以編程方式從nuget下載nupkg包？

在過去的.NET框架我用這個例子用的NuGet工作程序如何在.NET Core中以編程方式從nuget下載nupkg包？

是否有.NET睿任何等效源？

//ID of the package to be looked up 
string packageID = "EntityFramework"; 

//Connect to the official package repository 
IPackageRepository repo = PackageRepositoryFactory.Default.CreateRepository("https://packages.nuget.org/api/v2"); 

//Get the list of all NuGet packages with ID 'EntityFramework'  
List<IPackage> packages = repo.FindPackagesById(packageID).ToList(); 

//Filter the list of packages that are not Release (Stable) versions 
packages = packages.Where (item => (item.IsReleaseVersion() == false)).ToList(); 

//Iterate through the list and print the full name of the pre-release packages to console 
foreach (IPackage p in packages) 
{ 
    Console.WriteLine(p.GetFullName()); 
} 

//--------------------------------------------------------------------------- 

//ID of the package to be looked up 
string packageID = "EntityFramework"; 

//Connect to the official package repository 
IPackageRepository repo = PackageRepositoryFactory.Default.CreateRepository("https://packages.nuget.org/api/v2"); 

//Initialize the package manager 
string path = <PATH_TO_WHERE_THE_PACKAGES_SHOULD_BE_INSTALLED> 
PackageManager packageManager = new PackageManager(repo, path); 

//Download and unzip the package 
packageManager.InstallPackage(packageID, SemanticVersion.Parse("5.0.0"));

我想以編程方式下載和安裝任何軟件包。
