I have had troubles getting the automated visual basic thingy to work. When you look at Microsoft’s website about the unity support they have this picture As you can see this is not a Unity Pro license, and the Visual Basic line is not there. Is this because the license is only a Personal?
Unity 5.2 features "Out of the box support for Visual Sudio Tools for Unity (aka UnityVS)
Unity has actually allowed you to use visual studio in place of monodevelop for a while. Unity 5.2 allows you to install visual studio when you download Unity. To switch from mono to Visual Studio go to Edit → Preferences → External Script Editor and select Visual Studio.
My Unity 5.2 Personal install also does not show the Visual Studio line but came bundled with Visual Studio.
However as far as I know Visual Studio and Visual Basic are not the same thing and neither Unity Personal nor Unity Pro support Visual Basic.
UnityScripts are no longer supported (Since version 1.9).
“C# being the predominant language in
the Unity ecosystem - the new Sample
Assets are in C#, the Unity
documentation will default to C# - we
removed our basic support for
UnityScript and Boo to better focus on
the C# experience. As a result, VSTU
solutions are now C# only and are much
faster to load.”
