ASP NET MVC Interview Questions

These are called scaffold templates as they allow us to build a functional data-driven website quickly. Views are responsible for the rendering of the appropriate UI. Models are usually used to transfer data back and forth between controllers and views.

Their answer may also touch on the transitive nature of inheritance — for example, the Ford class inherits from Car, which inherits from Vehicle. In general OOP terms, inheritance means that a class can be based on another class, with the child class taking on the attributes of the parent class. For example, coders can create a class called Vehicle, and then child classes called Truck, Car and Motorcycle — all of which inherit the attributes of Vehicle. A NuGet package, Glimpse helps find diagnostic, performance, and debugging information.

What is Database first approach in MVC using Entity Framework?

It provides some abstract/virtual members that the inheriting entities must implement, as well as a partial implementation for a functionality. For extra credit, job candidates might mention that this class can also declare fields. If developers are creating methods that they do not wish to use as Actions, then they need to decorate such methods with the “Non-Action” attribute. MVC default route contains only one route with the name “Default”. It maps the 1st segment of URL to controller name, 2nd segment of URL to controller action, the 3rd segment of URL to a parameter named as “id”.

HTTP was earlier used as a protocol for all types of clients. The use of JavaScript, Windows applications, and even mobile demanded a high consumption of HTTP. WebAPI technology applied the REST principles to expose the data over HTTP. The page life cycle of MVC starts with application initialization, followed by routing, instantiate, and execute controller. Finally, it reaches to locate and invoke the controller action, then applies instantiate and render view. Model logic is an essential part of the application that handles the logic for the application data.

What are the advantages of ASP.NET MVC?

It is not a good idea to put log files in the bin folder of an application, because every change will cause a pool restart. You will face performance problems and unless you already know this, it will be difficult to track down the reason. Such a framework can help to reduce the amount of handwritten code in a typical web application. ORM can be used when there are no extreme requirements for performance in an application, but there are some frameworks (e.g., Dapper) which can be used even in high-load systems. Global level – By registering your filter into the Application_Start event of Global.asax.cs file with the help of FilterConfig class as shown below.

DataAnnotation plays a vital role in added validation to properties while designing the model itself. This validation can be added for both the client side and the server side. It indicates whether more than one instance of the error filter attribute can be specified. When you create a project a folder structure gets created by default under the name of your project which can be seen in solution explorer.

What is Bundling and Minification in MVC?

There are several answers, because ASP.NET Core is a new platform and supports several approaches. 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.

Some people also use them for wrapping business logic, sharing the model with an ORM tool. But it’s better to use the model only for transfering data (as a data transfer object) and as a validation contract (by marking the model’s properties with data annotation attributes). The HandleErrorAttribute is added to the GlobalFilters collection in global.asax. When a filter is added to the GlobalFilters collection, then it is applicable for all controllers and their action methods in the entire application.

  • Also, Microsoft provides several packages to help with this.
  • A session object is used for maintaining a user’s session, while an application object maintains use for an entire application.
  • Make sure to state the reasons why you feel that .NET is the right career for you and how you plan to use it to add value to the firm you just gave the .NET interview for.
  • State management, as the name suggests, is used to constantly monitor and maintain the state of objects in the runtime.

Using this dll you can also use this technique with ASP.NET MVC3 and .NET Framework 4.0. We can also enable the client-side validation programmatically. For this we need to do code within the Application_Start() event of the Global.asax, as shown below. Razor is the new view-engine introduced by MVC3, which acts as pluggable modules and applies different template syntax options.

What is JsonResultType in MVC?

NET Core is an open-source and core training cross-platform that runs on Windows, Linux, and Mac to develop modern cloud-based applications including IoT apps, Web Apps, Mobile Backends, and more. It is the fastest web development framework from NodeJS, Java Servlet, PHP in raw performance, and Ruby on Rails. Using the IServiceProvider interface we can easily add our own dependency injection container. We can replace the default implementation with our own container. The Controllers Folder contains the controller classes responsible for handling user input and responses. MVC requires the name of all controllers to end with “Controller”.
