>In C# it is not highlighted by default. If it is in your setup you can change it using : Tools/Options/Environment/Fonts and Colors/TextEditor/Highlight Current Line(Active) (and/or Highlight Current Line (Inactive)...

I see the option. But, it is not clear what to do next. I highlighted that option and clicked OK. If I go back in there, I do not see it as selected. This also does not change anything in the actual opened .vb files or on opening the new ones. I also restarted the project. There has to be something else to do when highlighting that setting.

Does it work for you?
