View: It contains the layout page. Before any view is rendered, viewstart page is rendered. View might have markup tags like body, html, head, title, meta etc. View is not lightweight as compare to Partial View. Partial View: It does not contain the layout page. Partial view does not verify for a viewstart.cshtml.We cannot put common code for a partial view within the viewStart.cshtml.page. Partial view is designed specially to render within the view and just because of that it does not consist any mark up. We can pass a regular view to the RenderPartial method.

Routing is a mechanism to process the incoming url that is more descriptive and give desired response. In this case, URL is not mapped to specific files or folder as was the case of earlier days web sites. There are two types of routing (after the introduction of ASP.NET MVC 5). Convention based routing:  to define this type of routing, we call MapRoute method and set its unique name, url pattern and specify some default values. Attribute based routing:  to define this type of routing, we specify the Route attribute in the action method of the controller.

ASP.NET MVC provides the following action filters: Output Cache:  This action filter caches the output of a controller action for a specified amount of time. Handle Error:  This action filter handles errors raised when a controller action executes. Authorize:  This action filter enables you to restrict access to a particular user or role.

In MVC, controllers define action methods and these action methods generally have a one-to-one relationship with UI controls such as clicking a button or a link, etc. For example, in one of our previous examples, the UserController class contained methods UserAdd, UserDelete, etc. But many times we would like to perform some action before or after a particular operation. For achieving this functionality, ASP.NET MVC provides feature to add pre and post action behaviors on controller's action methods. Types of Filters: ASP.NET MVC framework supports the following action filters: Action Filters:  Action filters are used to implement logic that gets executed before and after a controller action executes. We will look at Action Filters in detail in this chapter. Authorization Filters:  Authorization filters are used to implement authentication and authorization for controller actions. Result Filters:  Result filters contain logic that is executed before and after a view...
