ASP NET MVC Interview Questions
In .NET, unit testing involves testing singular units of code in isolation by writing tests that invoke methods and classes to see if they are working as expected. In .NET Entity Framework, the “model first” feature allows you to create complex database schemas using the visual designer. The visual designer allows you to create tables, relationships, and other elements needed to create a database schema. The model is then mapped to a database in a round-trip engineering method.
We can enable and disable optimizations by setting the EnableOptimizations property of BundleTable class to true or false within Global.asax.cs file as shown below. It is best practice to create a partial view in the shared folder and the partial view name is preceded by “_”, but it is not mandatory. The “_” before view name specifies that it is a reusable component i.e. partial view. By using the HttpMethod property of HttpRequestBase class, you can find out whether an action is invoked by HTTP GET or POST. All public methods of a Controller in ASP.NET MVC application that respond to the incoming URL are considered as Action Methods. If you are visiting ASP.NET forums and communities, we will find the following questions frequently i.e.
What is the difference between LINQ to SQL and Entity Framework?
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 Strongly typed HTML helper methods provide compile-time error checking. In most of the real-time application, we use strongly typed views, so we prefer to use Html.TextBoxFor over their counterpart HTML.TextBox. If you are going for an ASP.NET MVC interview, then you definitely face this question i.e. So here you need to explain how a request is handled in the ASP.NET MVC framework.
We have discussed some of the built-in action filters in the previous sessions of this series. The Exception filters are executed when an exception occurs during the action execution or filter execution. So if we need to add pre-and post-processing logic to an action method, then we need to use action filters. In Asp.net MVC, we can easily apply validation to the web application by using Data Annotation attribute classes to the model class. When the routing engine finds a match in the Route table for the incoming URL, then it forwards that request to the appropriate controller and action method.
What Is an Interface In .NET And How Is It Different from A Class?
Once the Routing engine receives the HTTP Request, then it figures out the URL Pattern of the incoming request and checks if that URL pattern is present in the Route table. If there is no matching URL Pattern found in the how to become a .net mvc developer routing table for the incoming HTTP request URL Pattern, then it simply returns a 404 HTTP status code to the client. The Controller is the component in the MVC design pattern which contains the control flow logic.
We’ll cover both general, c# MVC interview questions, and MVC 5 interview questions. It follows the MVC design pattern using the basic features of a core spring framework, including dependency injection and inversion of control. Here, we’ve rounded up the top MVC interview questions and answers for your MVC interview.
