View components can now be invoked as Tag Helpers.
- [Instructor] While view components themselves…didn't change in 1.1,…what changes they can now be invoked as a tag helper.…To do this, they must be registered in ViewImports.cshtml,…and it's the same way we registered the custom tag helpers.…So you add the line, addTagHelper*…for all of the view components that it finds…and then the assemblyname.…When you invoke them as a tag helper,…Pascal-cased names are changed to lower-kebab-case.…
So for example, our view component…is named categories-as-menus view component.…When you lower-kebab that as if it was on a shish kebab,…it becomes, as what you see on your screen,…categories-as-menus, dropping the view component suffix.…And then the tags themselves start with vc.…So we go back into our code.…Our view component itself hasn't changed.…There's the name, CategoriesAsMenusViewComponent.…
We look at the ViewImports.…Here on line 7, we have the addTagHelper.…We actually added this again for the custom tag helper…we wrote, but this same line is used…to register the view components.…
