How to upgrade NuGet in Visual Studio 2013

Ran into the following error during the Google Cloud Platform Bookshelf tutorial:

Error 1 NuGet Package restore failed for project 2-structured-data: The 'Microsoft.NETCore.Platforms 1.0.1' package requires NuGet client version '2.12' or above, but the current NuGet version is '2.8.50926.663'..

Where do I update NuGet?

How do I update NuGet to latest version?

Right-click the Packages folder in the project, and select Update. This will update the NuGet package to the latest version. You can double-click the Add packages and choose the specific version.

Found it in the menu under Tools -> Extensions and Updates -> Updates tab -> Visual Studio Gallery.
