Ensure that you have a shared location accessible to all developers in your organization. This can be anywhere your network administrator has provided for shared file access. You will probably want to restrict the access of these packages to developers only. A nice solution is to create a storage account on Azure to share the NuGet packages to. This is the approach I followed here using a fictitious company I have called Acme Corporation.
I will not go through setting up a storage account on Azure, but I will talk about accessing it from your local machine.
