What is MVC filter , how you implemented it in your app

Question

Accepted Answer

MVC filter is a feature in MVC framework that allows you to apply cross-cutting concerns to actions and controllers.

MVC filter is used to implement cross-cutting concerns like logging, authentication, authorization, etc.
It can be implemented by creating a custom filter class that inherits from the FilterAttribute class.
The custom filter class can override the OnActionExecuting, OnActionExecuted, OnResultExecuting, and OnResultExecuted methods to add the desired functionality.
The filter can be applied globally to all actions and controllers or selectively to specific actions or controllers using attributes.
Example: Creating a custom authorization filter to restrict access to certain actions based on user roles.
