• It helps to retrieve the value from the various configuration sources like XML file.
• These classes contains methods known as “Actions” which responds to the user action accordingly.

Next, we simply need to update the HandleErrorAttribute on the action method. Then, your action method needs to be marked with the atttribute. Contains Classes such as FilterConfig, RoutesConfig, WebApiConfig. This class contains the default format of the url that should be supplied in the browser to navigate to a specified page. The ValidationSummary helper method generates an unordered list of validation messages that are in the ModelStateDictionary object. It’s very simple to implement, just open the RouteConfig.cs file and you will find the routing definition in that. It creates a View with a form that helps in editing the current Model.

He is fascinated by clean architecture, TDD, DDD and CQRS. The Global.asax file is used to execute the application-level events and sets application-level variables.

• This validation has occurred before the Web page is sent to the server.
• The parser is smart enough to infer this from your code.
• Other popular ASP.NET MVC view engines are Spart & Nhaml.
• For those enterprises that lack certain specialists we provide services that help them acquire needed programmers to their teams.
• While implementing an MVC project, what are the steps needed for execution?
• A route defines the URL pattern and a handler which checks the request matching the pattern.

The candidate has to stress that, in the project, we need to use some kind of distributed cache—for example, Redis. Also, Microsoft provides several packages to help with this. In the case of Redis, Microsoft.Extensions.Caching.Redis provides the middleware and implements IDistributedCache to provide a standardized way to work with it. Authorization, custom action filters , and action result transformation can be done with the same approach. Application development process with ASP.NET MVC is more complex compared with web forms-based applications. The Controller processes this request by calling the service methods, and a ModelAndView object is returned by the DispatcherServlet. Here in mvc_servlet, the request is sent to the bean object, which acts as a model layer.

Q4. What is Razor View Engine? What are the possible file extensions used for razor views?

Action methods on controllers return JsonResult that can be used in an AJAX application.

• However, it is inappropriate for large projects since monolith may be imagined as one building where everything is stored.
• View– It represents the user interface with which end-users communicate.
• You could change the method body to conditionally return a RedirectResult or something else without changing the method definition.
• In ASP.NET MVC 5.0 we have a new attribute route,cBy using the “Route” attribute we can define the URL structure.
• The full form of ASP.NET AJAX is Asynchronous JavaScript and XML.

Junior becomes a middle dev when they successfully got acquainted with the whole technology stack that their team uses. A middle developer can solve many tasks autonomously, perform code review which was written by other colleagues.

Can you explain the page life cycle of MVC?

Asp.Net Web Form follow a traditional event-driven development model whereas Asp.Net MVC is a lightweight and follows MVC pattern based development, model. Cross-page posting means that you are posting form data to another page as opposed to posting form data back to the same page (as is the default in ASP.NET). ASP.NET Core is the https://remotemode.net/ Open-Source version of Microsoft ASP.NET. You can develop and run your ASP.NET Core apps cross-platform on Windows, Mac and Linux.

You become more confident at taking and cracking interviews. Register for our technical interview webinar to learn how to ace your tech interview prep.

Bootstrap Validation: How to validate a form using Bootsrap?

Area is used to store the details of the modules of our project. This is really helpful for big applications, where controllers, views and models are all in main controller, view and model folders and it is very difficult to manage. Action Filters allow us to execute the code before or after action has been executed. This can be done by decorating the action methods of controls with ASP.Net MVC attributes.

Increased developer productivity, this is because the base implementation of activities such as connecting to the database, sanitizing user input, etc., are already partially implemented. The best practice is to have controllers based on functionality. For example, if you have a form for input and you need a controller for that, create a controller called “form controller”. The Controller represents the layer that has the business logic. User events trigger the functions which are stored inside your controller. A route attribute is defined on top of an action method.
