Developers use tools like Apache JMeter or Microsoft’s Load Testing Service to conduct these tests. Swagger (OpenAPI) is a specification and tooling ecosystem for designing, building, documenting, and consuming RESTful APIs. In .NET MVC, Swagger can automatically generate interactive API documentation, client SDKs, and server stubs, facilitating API development and integration.

MVC also supports third-party view engines like Spark, Nhaml, NDjango, SharpDOM and so on. This return type is used to redirect to any other controller and action method depending on the URL. This request object is sent to “MvcHandler” instance to create the controller class instance. Once the controller class object is created it calls the “Execute” method of the controller class. Any web application has two main execution steps, first understanding the request and depending on the type of the request sending out an appropriate response. MVC application life cycle is not different it has two main phases, first creating the request object and second sending our response to the browser.

Top 50 .NET MVC Interview Questions and Answers for A .NET Developer

Strongly-typed views utilize a specific model class, enabling IntelliSense support, compile-time error checking, and type safety. They require declaring the model type at the top using “@model” directive, followed by the fully-qualified model name. This approach reduces runtime errors and enhances maintainability. Displaying shared content across multiple pages, such as headers, footers, or navigation menus. Breaking down complex views into smaller, more manageable pieces to improve readability and maintainability.

Redis is an in-memory data structure store used as a caching layer in .NET MVC applications. It provides fast read and write access, thus allowing frequently accessed data to be stored and retrieved quickly to improve application performance. This enables them to access resources in a .NET MVC application securely. React, and Angular are popular front-end JavaScript frameworks that can be integrated with .NET MVC. They provide powerful tools for building dynamic and interactive user interfaces taking advantage of concepts like component-based architecture and virtual DOM diffing. Load testing involves simulating high levels of user traffic to measure the performance and stability of a .NET MVC application.

They do this by applying attributes or aspects to target methods or classes in a .NET MVC application. Form submissions in .NET MVC are handled via the HttpPost attribute on the action method as well as the ValidateAntiForgeryToken attribute for CSRF protection. The form data is bound or linked to the model using model binding in ASP.NET MVC. They should understand the separation of concerns and efficient data flow in the model-view-pattern application architecture. Partial View in MVC is the chunk of HTML that can be applied in the current DOM.

Caching in .NET MVC can be implemented using the “OutputCache” attribute. As it does this, it improves app performance by serving cached content instead of re-executing the action unnecessarily. C# interview questions also test a candidate’s knowledge of new updates in the language that is crucial to their success in developing modern .NET applications. This may include nullable reference types, pattern matching, functional pipelines, and updated lambda expressions.

Define POST and GET action types.

Routing in ASP.NET MVC is responsible for mapping incoming HTTP requests to appropriate controller actions, enabling clean and user-friendly URLs. It uses a route table containing patterns that define the structure of expected URLs. URL generation creates URLs based on routing rules, ensuring consistency across the application. ActionResult is the base class for all result types returned from controller actions in .NET MVC. Routing in .NET MVC usually maps URLs to the controller actions in applications.

  • Application_BeginRequest and Application_EndRequest occur at the start and end of each HTTP request, useful for implementing custom logic like authentication or logging.
  • Define a static extension method with ‘this’ keyword for HtmlHelper parameter.
  • The paths in this library are recorded through the RegisterRoutes method.
  • This class receives incoming requests and maps them to view models and controllers.

TempData persists data until it’s read or the session ends, making it suitable for scenarios like redirecting between actions. The Razor View Engine is a markup syntax used in ASP.NET MVC for creating dynamic web pages. It combines C# or VB.NET code with HTML, enabling seamless server-side logic execution within the view.

Define ORM and give its use.

Visual Studio is equipped with various debugging features for .NET MVC, such as breakpoints, inspecting variables, stepping through code, and viewing call stacks. The Visual Studio debugger makes identifying and troubleshooting issues in a development environment easier. NuGet is a package manager used across .NET, including the ASP.NET MVC framework. It simplifies the addition and management of external libraries and dependencies in a .NET MVC project. The first constraint to a route is a regular expression, and the second constraint is an object that implements the IRouteConstraint interface. The route pattern is registered through a call to the MapRoute extension method of the RouteCollection.

  • This allows more flexibility and better organization of routing rules.
  • Razor View Engine firstly executes the _ViewStart and then start rendering the other view and merges them.
  • POST, on the other hand, is designed for submitting data to the server, often resulting in a change of state or creation of resources.
  • It generates a view that displays the label and an input field of the each property of the Model in the MVC framework.
