Top 25 ASP NET Core MVC Interview Questions and Answers

Visual Studio 2013 includes pre-installed code generators for MVC and Web API projects. You add scaffolding to your project when you want to quickly add code that interacts with data models. Using scaffolding can reduce the amount of time to develop standard data operations in your project.

  • The use of JavaScript, Windows applications, and even mobile demanded a high consumption of HTTP.
  • As businesses increasingly target multiple platforms, your ability to develop applications that work seamlessly on various devices and operating systems becomes a valuable asset.
  • This function is required when we call render() manually before the end of a given action.
  • When an incoming request arrives, the framework matches it against the route table.
  • Kestrel is a cross-platform, lightweight web server for ASP.NET Core applications.

Examples of reference types include object, string, arrays, and user-defined classes. As a .NET developer, you’ll be working extensively with C#, so it’s essential to understand the language’s core concepts and features.

When approaching code reviews, my primary focus is on understanding the intent behind the changes made by the developer. This helps me provide constructive feedback that aligns with their goals while ensuring the code meets our quality standards. I pay close attention to aspects such as readability, maintainability, and efficiency, as well as checking for any security how to become a .net mvc developer vulnerabilities or potential bugs. I have worked extensively with tools like Jenkins, TeamCity, and Azure DevOps to automate the build, test, and deployment stages of our applications. Additionally, I’ve integrated version control systems such as Git and SVN into the pipeline to ensure seamless tracking of changes and efficient collaboration among team members.

Create a ShoppingCartSummaryViewComponent class inheriting from ViewComponent. Implement InvokeAsync() method with the required logic to retrieve cart data and calculate totals. In the shared layout or specific views, call the view component using @await Component.InvokeAsync(“ShoppingCartSummary”).

Data Annotations allow us to decorate model classes with metadata.

The value of authentication cookie contains a string representation of the encrypted and signed FormsAuthenticationTicket object. ASP.NET MVC has always supported the concept of “view engines” – which are the pluggable modules that implement different template syntax options. The “default” view engine for ASP.NET MVC uses the same .aspx/.ascx/.
