Using The Package Manager Console. This topic describes how to find, install, remove, and update NuGet packages using PowerShell commands.
You can also work with packages using the Manage NuGet Packages dialog box. For more information, see [Using the Manage NuGet Packages dialog](Using-the Add-Library-Package-Reference-Dialog-Box). Using PowerShell commands is required if you want to install a package without having a solution open. It's also required in some cases for packages that create commands that you can access only by using PowerShell.
