View components are another brand-new feature in ASP.NET Core that combines server code with view code to encapsulate chunks of the response.
- [Instructor] Another new feature in ASP.NET Core…are View Components, and these combine…server-side code with partial views…and are used to render a chunk of the response.…Some common uses are dynamically created menus,…like in the sample app provided for you,…a login panel or a shopping cart.…There are some limitations.…They can't serve as a client-side end point,…they don't use model binding, and they don't participate…in the controller lifecycle.…
So, they're very similar to child actions,…which have gone away, combined with partial views.…To create a ViewComponent class,…create a new public, non-nested, non-sealed class,…and those are actual requirements.…Derive from ViewComponent.…You don't have to derive from ViewComponent,…there's some other games you can play,…but really, to get the most value out of a view component,…you should derive from a ViewComponent.…And then, you implement the InvokeAsync…and return an IViewComponentResult,…which is typically a view.…
Any data needed for the view…needs to be passed into the view as a viewmodel,…
