In order to be able to manage your projects' packages, you need the NuGet Package Manager. This is a Visual Studio Extension, explained in the official docs: Installing and Updating NuGet Client.
Starting with Visual Studio 2012, NuGet is included in every edition, and can be used from: Tools -> NuGet Package Manager -> Package Manager Console.
You do so through the Tools menu of Visual Studio, clicking Extensions and Updates:

And the Package Manager Console:
When you right-click a project (or its References folder), you can click the "Manage NuGet Packages..." option. This shows the Package Manager Dialog.
Click the menus Tools -> NuGet Package Manager -> Package Manager Console to show the console in your IDE. Official documentation here.
Here you can issue, amongst others,
install-package commands which installs the entered package into the currently selected "Default project":
You can also provide the project to install the package to, overriding the selected project in the "Default project" dropdown:
Install-Package Elmah -ProjectName MyFirstWebsite
To update a package use the following command:
PM> Update-Package EntityFramework
where EntityFramework is the name of the package to be updated. Note that update will run for all projects, and so is different from
Install-Package EntityFramework which would install to "Default project" only.
You can also specify a single project explicitly:
PM> Update-Package EntityFramework -ProjectName MyFirstWebsite
PM> Uninstall-Package EntityFramework
PM> Uninstall-Package -ProjectName MyProjectB EntityFramework
PM> Install-Package EntityFramework -Version 6.1.2
