Deploying modules and scripts compressed into a NuGet package and upgrading them later on is very easy once an infrastructure is in place and can be accessed. In the following sections, we will have a look at what it means to interact with package repositories. PackageManagement and PowerShellGet are the key components in this section, and we will examine them a little more.
PowerShellGet is the key component to find, install, upgrade, and remove PowerShell scripts, modules, and DSC resources. Additionally, it provides cmdlets to add documentation data to scripts and modules and update them later. All cmdlets are vital components of a PowerShell module release pipeline.
PowerShellGet operates with the NuGet and Chocolatey repositories, and PackageManagement further extends this with additional package providers to handle MSI and MSU files:
