Visual Studio 2015 is giving me an error stating that the "Namespace or type specified in the Imports 'Microsoft.Office.Interop.Excel' doesn't contain any public member or cannot be found." I just started getting this error after upgrading to Office 2016 from 2013.

I don't have a .NET tab in my References section to add this reference. MSDN is only giving me an option to download the Primary Interop Assembly for Visual Studio 2013 and it is not fixing my issue. I still don't see the .NET tab.

How do I fix these reference errors?
