Partial Views and Child Actions are one the most used features of ASP.NET MVC. Partial Views provides us a way to create a reusable component that can be used in multiple Views. There are Actions which can be marked as Child Actions and these cannot be invoked via URL but inside views or partial views. Child Actions are no more available with ASP.NET Core. View Components are new way to implement this feature in ASP.NET Core.
