We pass the essential URL and data with all the POST requests. ORM (object-relational mapping) framework is a framework that helps in reducing the amount of handwritten code in a web app. ORM is used when there are no extreme performance requirements, but frameworks like Dapper can be used in high-load systems. In layman’s terms, the partial view allows rendering a view within the parent view. ( Not specific to authentication/Authorization/Action/Exception). For example, inside an Action method in your controller, you will be returning like below.

  • A partial view is a chunk of HTML that can be safely inserted into an existing DOM.
  • Using object which implements interface — IRouteConstraint.
  • Model represents the real world object and provides data to the view.
  • Kestrel is an event-driven, I/O-based, open-source, cross-platform, and asynchronous server which hosts .NET applications.
  • This return type is used when we want to return a JSON message.
  • This class contains the default format of the url that should be supplied in the browser to navigate to a specified page.

This will reduce the coding in case of changes on project design so this is vastly used. Similar to Keep method we have one more method called “Peek” which is used for the same purpose. This method used to read data in Tempdata and it maintains the data for subsequent request. Data annotations are attributes which can be found in the “System.ComponentModel.DataAnnotations” namespace. These attributes will be used for server-side validation and client-side validation is also supported. Four attributes – Required, String Length, Regular Expression and Range are used to cover the common validation scenarios. View Model is a plain class with properties, which is used to bind it to strongly typed view.

The easiest way to render an HTML link in is to use the HTML.ActionLink() helper.With MVC, the Html.ActionLink() does not link to a view. Requires typecasting for complex data types and checks for null values to avoid an error. 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.
