I\'m following this easy tutorial to start coding with the Google+ API in C#. However, I\'ve been stuck for hours on Step 3, where the first substeps are:
If you right-click on a project, and don't see the option to "Enable Nuget Package Restore", The reason why you do not SEE this option is because you do not have the latest version of nuget package installed in Visual Studio.
The following steps will show you how to install the appropriate nuget package for the version of Visual Studio you are using. Click on Tools->Extensions and Update. Extensions and Update Dialog will appear. Click on online in the left hand column of the dialog. You should see as first package in list "Nuget Package Manager for Visual Studio 2013. Click on the 'download' button to install. You may then have to restart Visual Studio.
Now re-open your solution and right-click on the solution name. You should now see a dialog popup asking you if you want to restore packages for this solution. If you select 'yes' then anytime you build your solution nuget will attempt to download and of the corresponding packages your solution is using.
