What is main use of ChildActionOnly in mvc?

Accepted answer

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request

In short sentence you can't access direct ChildAction like Home/ChildAction. it will give you Authorisation Issue. it will use in main method of Controller.

Generally we can use it in Payment Gateway Class
