Installing NuGet packages manually?

Question

_{Friday, December 8, 2017 7:15 PM}

I'm trying to install ValueTuple nuget package manually without internet connection:

https://www.nuget.org/packages/System.ValueTuple/

But getting an error:

Install-Package System.ValueTuple -Source N:\
 
 
Attempting to gather dependency information for package 'System.ValueTuple.4.4.0' with respect to project 'Advent7', targeting '.NETFramework,Version=v4.6.1'
Install-Package : Exception 'System.AggregateException' thrown when trying to add source 'https://api.nuget.org/v3/index.json'. Please verify all your online package sources are available.
  One or more errors occurred.
  Unable to load the service index for source https://api.nuget.org/v3/index.json.
  An error occurred while sending the request.
  Unable to connect to the remote server
  An attempt was made to access a socket in a way forbidden by its access permissions 93.184.221.200:443

+ Install-Package <<<<  System.ValueTuple -Source N:\
    + CategoryInfo          : NotSpecified: (:) [Install-Package], Exception
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

Apparently it still wants to connect. How can I avoid that? My project targets .NET Framework 4.6.1 so it should be good on dependencies.

Hi,

Please make sure that you have created a local nuget repository for offline development.

• Firstly, you’ll need to create a local folder to house all your local NuGet packages.
• The next step is to download the NuGet packages you wish to be able to use offline into this folder.(need network connection)
• Once you have successfully downloaded the .nupkg files you require into your local repository folder, head into Visual Studio and open the NuGet Settings dialog via Tools > NuGet Package Manager > Package Manager Settings. Click the Package Sources tab within the settings dialog, followed by the ‘plus’ icon in the top left to add a new package source.
• Now that you have added the local package source, you will be able to use your offline local repository from within Visual Studio in the usual way.
